+Problems with old systems that have known work-a-rounds:
+
+    * The gcc as shipped with Redhat 7 perhaps other Linux distributions
+      has a bug causes calc to dump core on startup when calc is:
+
+	  compiled optimized (-O, -O1, -O2 or -O3)
+
+	  	AND
+
+      	  compiled with debugging (-g or -g3)
+
+	  	AND
+
+	  when calc is compiled with readline (see USE_READLINE,
+	  READLINE_LIB and READLINE_INCLUDE in the Makefile)
+
+      This is known as the Redhat 7 readlne problem.
+
+      On Redhat, the gcc -v which has this problem is:
+
+	gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)
+
+      there may be other gcc versions that also suffer this fate.
+
+      The readlines associated with problem are:
+
+	readline-4.1-5
+	readline2.2.1-2.2.1-2
+	readline-devel-4.1-5
+
+      One work-a-round is to compile calc WITHOUT readline.  In the
+      Makefile be sure that:
+
+	USE_READLINE=
+	READLINE_LIB=
+	READLINE_INCLUDE=
+
+      i.e., these Makefile vars are empty.
+
+      If you must use readline, then an alternate work-a-round is to
+      change the DEBUG Makefile variable to either:
+
+	compile for speed:  -O3		(or -O2 if you do not have -O3)
+	compile to debug:   -g3		(or -g if you do not have -g3)
+
+      but not both.
+
+      See RH bug #57889 for details:
+
+	http://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=57889
 
     * There is a bug in gcc-2.95 that causes calc, when compiled with -O2,
       to fail the regression test.  The work-a-round is to compile with -O
       or to use gcc-2.96 or later.
 
+      This bug has been observed on the Sparc and the PowerPC machine.
+
+      On the PowerPC with gcc-2.95 when compiled with -O2, the following

-	   include files and calc libs are to be installed.  As shipped
+	        - calc source in RPM package form
-	   the Makefile assumes a TOPDIR of /usr/local/lib.
 
-	   Set BINDIR to the place where calc is installed.  As shipped

-	   the Makefile assumes a BINDIR /usr/local/bin.

+		gunzip -c calc-*.tar.gz | tar -xvf -
+
+	or from:
+
+		rpm -ivh calc-*.src.rpm
+		cd /var/tmp
+		gunzip -c /usr/src/redhat/SOURCES/calc-*.tar.gz | tar -xvf -
+
+    1)	Look at the makefile, and adjust it to suit your needs.
+
+	The Makefile, as shipped, is suitable for installation under
+	Linux and Un*x-like environments.  For the most part, the default
+	values should work.  If in doubt, follow the 'When in doubt'
+	suggestion.
+
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+	! If you are building under Windoz or a Windoz-like environment !
+	! (such as Cygwin or DJGPP), read the README.WINDOWS file.      !
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+	You should determine if these Makefile variables are reasonable:
+
+	    INCDIR		Where the system include (.h) files are kept.
+	    BINDIR		Where to install calc binary files.
+	    LIBDIR		Where to install calc link library (*.a) files.
+	    CALC_SHAREDIR	Where to install calc help, .cal, startup, and
+	    			config files.
+
+	You may want to change the default installation locations for
+	these values, which are based on the 4 values listed above:
+
+	    HELPDIR            where the help directory is installed
+	    CALC_INCDIR        where the calc include files are installed
+	    CUSTOMCALDIR       where custom *.cal files are installed
+	    CUSTOMHELPDIR      where custom help files are installed
+	    CUSTOMINCPDIR      where custom .h files are installed
+	    SCRIPTDIR          where calc shell scripts are installed
+
+	If you want to install calc files under a top level directory,
+	then set the T value:
+
+	    The calc install is performed under $T, the calc build is
+	    performed under /.	The purpose for $T is to allow someone
+	    to install calc somewhere other than into the system area.
+
+	    For example, if:
+
+	    	BINDIR= /usr/bin
+		LIBDIR= /usr/lib
+		CALC_SHAREDIR= /usr/share/calc
+
+	    and if:
+
+	    	T= /var/tmp/testing
+
+	    Then the installation locations will be:
+
+		calc binary files:	/var/tmp/testing/usr/bin
+		calc link library:	/var/tmp/testing/usr/lib
+		calc help, .cal ...:	/var/tmp/testing/usr/share/calc
+		... etc ...		/var/tmp/testing/...
+
+	    If $T is empty, calc is installed under /, which is the same
+	    top of tree for which it was built.  If $T is non-empty, then
+	    calc is installed under $T, as if one had to chroot under
+	    $T for calc to operate.
+
+	Look for the section that starts:
+
+	    ################
+	    # compiler set #
+	    ################
+
+	    Select a compiler set by commenting in the appropriate set
+	    of cc options.  As shipped the Makefile assumes a gcc-like
+	    environment such as Linux.  If a more appropriate cc set if
+	    found below, comment out the Linux set and comment in that
+	    set or edit the gcc set or the common cc set as needed.
+
+	You may want to change these Makrfile variables from their defaults:
+
+	    RANLIB
+
+		You may or may not need RANLIB when building libraries.
+		As shipped the Makefile assumes RANLIB is needed.
+		Comment the in/out the RANLIB value if ranlib does
+		not work or does not exist.
+
+	    CALCPAGER

+		You may want to change the default pager used by calc.
+		As shipped the Makefile assumes 'more'.  On your system
+		you may find 'less' to be a better pager.
+
+	    DEBUG
+
+	       Some compilers (to put it mildly) have bugs.  Sometimes the
+	       DEBUG Makefile variable causes the compiler / optimizer to
+	       produce bad code.  Other compilers do just fine.

+Dear calc user on a Windoz based system,
+
+See the HOWTO.INSTALL file for information on how to build and install calc.
+See also the README file.
+
+NOTE: The main developers do not have access to a Windoz based platform.
+      While we will make an effort to not break calc Windoz based system,
+      our lack of a Windoz test environment will mean we will make mistakes
+      from time to time.  Hopefully Windowz users can overcome these mistakes.
+      Of course you are welcome to send us any patches that fix your
+      Windoz build environment.

+=-= compiling under DJGPP =-=
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+You might want to try using the DJGPP system to compile calc.  See:
+
+	http://www.delorie.com/djgpp/
+
+for DJGPP details and availability.
+
+To compile with DJGPP, one needs to select a number of Makefile
+variable changes.  Eli Zaretskii <eliz at is dot elta dot co dot il>
+recommends the following settings:
+
+	TERMCONTROL= -DUSE_TERMIOS
+	BYTE_ORDER= -DLITTLE_ENDIAN
+	LONG_BITS= 32
+	HAVE_FPOS_POS= -DHAVE_NO_FPOS_POS
+	FPOS_BITS= 32
+	OFF_T_BITS= 32
+	DEV_BITS= 32
+	INODE_BITS= 32
+	HAVE_USTAT= -DHAVE_NO_USTAT
+	HAVE_GETSID= -DHAVE_NO_GETSID
+	HAVE_GETPGID= -DHAVE_NO_GETPGID
+	HAVE_GETTIME= -DHAVE_NO_GETTIME
+	HAVE_GETPRID= -DHAVE_NO_GETPRID
+	HAVE_URANDOM_H= NO
+	ALIGN32= -UMUST_ALIGN32
+	HAVE_MALLOC_H= YES
+	HAVE_STDLIB_H= YES
+	HAVE_STRING_H= YES
+	HAVE_TIMES_H= NO
+	HAVE_SYS_TIMES_H= YES
+	HAVE_TIME_H= YES
+	HAVE_SYS_TIME_H= YES
+	HAVE_UNISTD_H= YES
+	BINDIR= /dev/env/DJDIR/bin
+	INCDIR= /dev/env/DJDIR/include
+	LIBDIR= /dev/env/DJDIR/lib
+	MANDIR= /dev/env/DJDIR/man/man1
+	CATDIR= /dev/env/DJDIR/man/cat1
+	NROFF= groff
+	CALCPATH= .;./cal;~/.cal;${CALC_SHAREDIR};${CUSTOMCALDIR}
+	CALCRC= ${CALC_SHAREDIR}/startup;~/.calcrc;./.calcinit
+	CALCPAGER= less.exe -ci
+	DEBUG= -O2 -gstabs+
+
+The 'Linux set' or 'gcc set' (see the Select your compiler type section)
+should work for DJGPP systems if you set the above Makefile variables.
+
+Look for Makefile comments of the form:
+
+	# Select ...something... for DJGPP.
+
+Follow those recommendations.  In cases where they conflict with
+the above Makefile list, follow the recommendation in the Makefile.

+=-= compiling with Cygwin =-=
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+An effort is being made to allow windows users to compile calc using the
+Cygwin project (http://sources.redhat.com/cygwin/) with the GCC compiler
+and Un*x tools for Windows.
+
+The major porting work was performed by Thomas Jones-Low
+(tjoneslo at softstart dot com).  He said:
+
+    I had previous stated to this group that I have successfully managed
+    to port a version of Calc to Windows, and promised some point to
+    post what was required, so here it is.
+
+    One obvious manner of doing this port is to get the latest version
+    of the Cygwin project (http://sources.redhat.com/cygwin/) with the
+    GCC compiler and Un*x tools for Windows and recompile.
+
+    I built my working version using Calc ... I am using Visual C++
+    version 7.0, which is an older version of the Microsoft development
+    tools. The make file provided with Calc is not compatible with
+    NMAKE, so I used the Visual Studio tools to generate another one
+    (not included). Calc is built in two parts, calc.dll, which is the
+    library, and calc.exe which is the command line interface.
+
+He recommended that you generate by hand all of the header files that
+by the Makefile.  This has been done for you via the makefile rule:
+
+	make win32_hsrc
+
+which uses the Makefile variables in win32.mkdef to form these header
+files under win32 directory.
+
+You will find generated versions of these files located in the win32
+sub-directory.  These files may be appropriate for your Cygwin building
+needs.
+
+In particular:
+
+	Just copy the win32/*.[ch] files up into the top level calc
+	source directory, edit them (if needed) and build using the
+	Cygwin GCC compiler and Cygwin build environment.
+
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+=-=-= calc maintenance folk =-=-=
+=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+People who maintain calc need to keep in mind the following:
+
+The following was added to opcodes.h, config.h, zmath.h and value.h:
+
+	#if defined(_WIN32)
+	#ifdef _EXPORTING
+	  #define DLL	__declspec(dllexport)
+	#else
+	  #define DLL	__declspec(dllimport)
+	#endif
+
+	#else /* Windoz free systems */
+
+	  #define DLL
+
+	#endif /* Windoz free systems */
+
+Then DLL was added in front of all the exported functions.  For example:
+
+    extern int configtype(char*);
+
+was changed to:
+
+    DLL extern int configtype(char*);

+NAME
+    pmodm127 - calculate q mod 2^(2^127-1)
+
+SYNOPSIS
+    custom("pmodm127", q)
+
+TYPES
+    q		int > 0
+
+    return	int
+
+DESCRIPTION
+
+    This custom function will return the value:
+
+    	q mod 2^(2^127-1)
+
+    This custom function serves as a demonstration of how to write
+    a custom function.  It performs the equivalent of:
+
+	pmod(2, 2^127-1, q)
+
+    The return value is integer in the half open range: [0, q).
+
+    SPECIAL NOTE:
+
+	Can you find a value, q, for which this custom function returns 1?
+	If you do, send the value of q to chongo using the EMail address
+	found at:
+
+	    http://www.isthe.com/chongo/address.html
+
+EXAMPLE

+
+SYNOPSIS

+
+TYPES
+    mode	real
+
+    return	real
+
+DESCRIPTION
+    By default, calc will output values according to the default base
+    as controlled by the base() builtin function.
+
+    The base2() builtin function, if given a non-zero argument, enables
+    double base output mode.  In double base output mode, calc values
+    are displayed twice, once according to base() and again according
+    to base2().  In double base output mode, the second time a value is
+    displayed, it is displayed within comments:
+
+	21701 /* 0x54c5 */
+
+    The arguments for base2() are identical to base() with the addition
+    of the 0 value:
+
+	     base2	equivalent
+		      config("mode2")'s
+
+	       2	"binary"	base 2 fractions
+			"bin"
+
+	       8	"octal"		base 8 fractions
+			"oct"
+
+	      10	"real"		base 10 floating point
+			"float"
+			"default"
+
+	     -10	"integer"	base 10 integers

+			"hex"
+
+	     1/3	"fraction"	base 10 fractions
+			"frac"
+
+	    1e20	"scientific"	base 10 scientific notation
+			"sci"
+			"exp"
+
+	       0	"off"		disable double base output
+
+    For convenience, any non-integer non-zero value is assumed to mean
+    base 10 fractions and any integer >= 2^64 is assumed to mean base 10
+    scientific notation.
+
+    These base2() calls have the same meaning as config("mode2", "fraction"):
+
+	base2(1/3)	base2(0.1415)	base2(16/37)
+
+    These base2() calls have the same meaning as config("mode2", "scientific"):
+
+	base2(1e20)	base2(2^64)	base2(2^8191-1)

+
+SYNOPSIS
+    bernoulli(n)
+
+TYPES
+    n		integer, n < 2^31 if even
+
+    return	rational
+
+DESCRIPTION
+    Returns the Bernoulli number with index n, i.e. the coefficient B_n in
+    the expansion
+
+		t/(exp(t) - 1) = Sum B_n * t^n/n!
+
+    bernoulli(n) is zero both for n < 0 and for n odd and > 2.
+    When bernoulli(n) is computed for positive even n, the values for
+    n and smaller positive even indices are stored in a table so that
+    a later call to bernoulli(k) with 0 <= k < n will be executed quickly.
+
+    Considerable runtime and memory are required for calculating
+    bernoulli(n) for large even n.  For n = 1000, the numerator has
+    1779 digits, the denominator 9 digits.
+
+    The memory used to store calculated bernoulli numbers is freed by
+    freebernoulli().
+
+EXAMPLE
+    > config("mode", "frac"),;

-Function definitions
+NAME
+    define - command keyword to start a function definition
 
-    Function definitions are introduced by the 'define' keyword.
+SYNTAX
-    Other than this, the basic structure of an ordinary definition
+    define fname([param_1 [= default_1], ...]) = [expr]
-    is like in that in C: parameters are specified for the function
+    define fname([param_1 [= default_1], ...]) { [statement_1 ... ] }
-    within parenthesis, the function body is introduced by a left brace,
-    variables may declared for the function, statements implementing the
-    function may follow, any value to be returned by the function is specified
-    by a return statement, and the function definition is ended with a
-    right brace.
 
-    There are some subtle differences, however.	 The types of parameters
+TYPES
-    and variables are not defined at compile time, and may vary during
+    fname		identifier, not a builtin function name
-    execution and be different in different calls to the function.  For
+    param_1, ...	identifiers, no two the same
-    example, a two-argument function add may be defined by
+    default_1, ...	expressions
+    expr		expression
+    statement_1, ...	statements
 
-		define add(a,b) {
+DESCRIPTION
-			return a + b;
+    The intention of a function definition is that the identifier fname
-		}
+    becomes the name of a function which may be called by an expression
+    of the form  fname(arg_1, arg_2, ...), where arg_1, arg_2, ... are
+    expressions (including possibly blanks, which are treated as
+    null values).  Evaluation of the function begins with evaluation
+    of arg_1, arg_2, ...; then, in increasing order of i, if arg_i is
+    null-valued and  "= default_i" has been included in the definition,
+    default_i is evaluated and its value becomes the value of arg_i.
+    The instructions in expr or the listed statements are then executed
+    with each occurrence of param_i replaced by the value obtained
+    for arg_i.
 
-    and be called with integer, fractional, or complex number values for a
+    In a call, arg_i may be preceded by a backquote (`)  to indicate that
-    and b, or, under some compatibility conditions, matrices or objects.
+    evaluation of arg_i is not to include a final evaluation of an lvalue.
-    Any variable, not already defined as global, used in a definition has
+    For example, suppose a function f and a global variable A have been
-    to be declared as local, global or static, and retains this character
+    defined by:
-    until its scope is terminated by the end of the definition, the end of
-    the file being read or some other condition (see help variable for
-    details).
 
-    For example, the following function computes the factorial of n, where
+		define f(x) = (x = 3);
-    we may suppose it is to be called only with positive integral values
+		global mat A[3];
-    for n:
 
-	    define factorial(n)
+    If g() is  a function that evaluates to 2:
-	    {
-		    local	ans;
 
-		    ans = 1;
+		f(A[g()]);
-		    while (n > 1)
-			    ans *= n--;
-		    return ans;
-	    }
 
-    (In calc, this definition is unncessary since there is a built-in
+    assigns the value of A[2] to the parameter x and then assigns the
-    function fact(n), also expressible as n!, which returns the factorial
+    value 3 to x:
-    of n.)
 
-    Any functions used in the body of the definition need not have already
+		f(`A[g()]);
-    been defined; it is sufficient that they have been defined when they are
-    encountered during evaluation when the function is called.
 
-    If a function definition is sufficiently simple and does not require
+    has essentially the effect of assigning A[2] as an lvalue to x and
-    local or static variables, it may be defined in shortened manner by
+    then assigning the value 3 to A[2].  (Very old versions of calc
-    using an equals sign following by an expression involving some or all
+    achieved the same result by using '&' as in  f(&A[g()]).)
-    of the parameters and already existing global variables.
 
-    In this case, the definition is terminated by a newline character
+    The number of arguments arg_1, arg_2, ... in a call need not equal the
-    (which may be preceded by a semicolon), and the value the function
+    number of parameters.  If there are fewer arguments than parameters,
-    returns when called will be determined by the specified expression.
+    the "missing" values are assigned the null value.
-    Loops and "if" statements are not allowed (but ? : expressions and the
-    logical operators ||, && and !  are permitted).  As an example, the
-    average of two numbers could be defined as:
 
-	    define average(a, b) = (a + b) / 2;
+    In the definition of a function, the builtin function param(n)
+    provides a way of referring to the parameters.  If n (which may
+    result from evaluating an expreession) is zero, it returns the number
+    of arguments in a call to the function, and if 1 <= n <= param(0),
+    param(n) refers to the parameter with index n.
 
-    (Again, this function is not necessary, as the same result is

+
+    The definitions of all user-defined functions may be removed by:
+
+		undefine *
+
+    If bit 0 of config("resource_debug") is set and the define command is
+    at interactive level, a message saying that fname has been defined
+    or redefined is displayed.  The same message is displayed if bit 1
+    of config("resource_debug") is set and the define command is read
+    from a file.
+
+    The identifiers used for the parameters in a function definition do
+    not form part of the completed definition.  For example,
+
+	define f(a,b) = a + b;
+	define g(alpha, beta) = alpha + beta;
+
+    result in identical code for the functions f, g.
+
+    If config("trace") & 8 is nonzero, the opcodes of a newly defined
+    function are displayed on completion of its definition, parameters
+    being specified by names used in the definition.  For example:
+
+	> config("trace", 8),
+	> define f(a,b) = a + b
+	0: PARAMADDR a
+	2: PARAMADDR b
+	4: ADD
+	5: RETURN
+	f(a,b) defined
+
+    The opcodes may also be displayed later using the show opcodes command;
+    parameters will be specified by indices instead of by names.  For example:
+
+	> show opco f
+	0: PARAMADDR 0
+	2: PARAMADDR 1
+	4: ADD
+	5: RETURN
+
+    When a function is defined by the statement mode, the opcodes normally
+    include DEBUG opcodes which specify statement boundaries at which
+    SIGINT interruptions are likely to be least risky.  Inclusion of
+    the DEBUG opcodes is disabled if config("trace") & 2 is nonzero.
+    For details, see help interrupt.
+
+    While config("trace") & 1 is nonzero, the opcodes are displayed as
+    they are being evaluated.  The current function is identified by its
+    name, or "*" in the case of a command-line and "**" in the case of
+    an eval(str) evaluation.
+
+    When a function is called, argument values may be of any type for
+    which the operations and any functions used within the body of the
+    definition can be executed.  For example, whatever the intention at
+    the time they were defined, the functions f1(), f2() defined above
+    may be called with integer, fractional, or complex-number values, or
+    with both arguments strings, or under some compatibility conditions,
+    matrices or objects.
+
+EXAMPLE
+    > define f(a,b) = 2*a + b;
+    > define g(alpha, beta)
+    >> {
+    >>	   local a, pi2;
+    >>
+    >>	   pi2 = 2 * pi();
+    >>	   a = sin(alpha % pi2);
+    >>	   if (a > 0.0) {

+    >>	   }
+    >>	   if (beta > 0.0) {
+    >>	       a *= cos(-beta % pi2);
+    >>	   }
+    >>	   return a;

 NAME
-    digit - digit at specified position in a decimal representation
+    digit - digit at specified position in a "decimal" representation
 
 SYNOPSIS
-    digit(x, y)
+    digit(x, n [, b])
 
 TYPES
     x		real
-    y		integer
+    n		integer
+    b		integer >= 2, default = 10
 
     return	integer
 
 DESCRIPTION
-    By extending the digits on the left, and if necessary, the digits
-    on the right, by infinite strings of zeros, abs(x) may be considered
-    to have the decimal representation:
 
-		... d_2 d_1 d_0.d_-1 d_-2 ...
+    d(x,n,b) returns the digit with index n in a standard base-b "decimal"
+    representation of x, which may be described as follows:
+
+    For an arbitrary base b >= 2, following the pattern of decimal (base 10)
+    notation in elementary arithmetic, a base-b "decimal" representation of
+    a positive real number may be considered to be specified by a finite or
+    infinite sequence of "digits" with possibly a "decimal" point
+    to indicate where the fractional part of the representation begins.
+    Just as the digits for base 10 are the integers 0, 1, 2, ..., 9, the
+    digits for a base-b representation are the integers d for which
+    0 <= d < b.   The index for a digit position is the count, positively to
+    the left, of the number from the "units" position immediately to the
+    left of the "decimal" point; the digit  d_n  at position n contributes
+    additively  d_n * b^n  to the value of x.  For example,
+
+		d_2 d_1 d_0 . d_-1 d_-2
+
+    represents the number
+
+		d_2 * b^2 + d_1 * b + d0 + d_-1 * b^-1 + d_-2 * b^-2
+
+    The sequence of digits has to be infinite if den(x) has a prime factor
+    which is not a factor of the base b.  In cases where the representation
+    may terminate, the digits are considered to continue with an infinite
+    string of zeros rather than the other possibility of an infinite
+    sequence of (b - 1)s.  Thus, for the above example, d_n = 0 for
+    n = -3, -4, ...  Similarly, a representation may be considered to
+    continue with an infinite string of zeros on the left, so that in the
+    above example d_n = 0 also for n >= 3.
+
+    For negative x, digit(x,n,b) is given by digit(abs(x),n,b); the
+    standard "decimal" representation of this x is a - sign followed by
+    the representation of abs(x).
+
+    In calc, the "real" numbers are all rational and for these the
+    digits following the decimal point eventually form a recurring sequence.
+
+    With base-b digits for x as explained above, the integer whose base-b
+    representation is
+
+		b_n+k-1 b_n_k-2 ... b_n,
+
+    i.e. the k digits with last digit b_n, is given by
+
+		digit(b^-r * x, q, b^k)
+
+    if r and q satisfy  n = q * b + r.
 
-    digit(x,y) then returns the digit d_y.
 
 EXAMPLE
-    > x = 12.34
+	> a = 123456.789
-    > print digit(x,2), digit(x,1), digit(x,0), digit(x,-1), digit(x,-2)
+	> for (n = 6; n >= -6; n++) print digit(a, n),; print
-    0 1 2 3 4
+	0 1 2 3 4 5 6 7 8 9 0 0 0
 
-    > x = 10/7
+	> for (n = 6; n >= -6; n--) print digit(a, n, 100),; print
-    > print digit(x,1), digit(x,0), digit(x,-1), digit(x,-2), digit(x,-3)
+	0 0 0 0 12 34 56 78 90 0 0 0 0
-    0 1 4 2 8
+
+	> for (n = 6; n >= -6; n--) print digit(a, n, 256),; print
+	0 0 0 0 1 226 64 201 251 231 108 139 67
+
+  	> for (n = 1; n >= -12; n++) print digit(10/7, n),; print
+    	> 0 1 4 2 8 5 7 1 4 2 8 5 7 1
+
+	> print digit(10/7, -7e1000, 1e6)
+	428571
 
 LIMITS
-    If x is not an integer, y > -2^31
+
+    The absolute value of the integral part of x is assumed to be less
+    than 2^2^31, ensuring that digit(x, n, b) will be zero if n >= 2^31.
+    The size of negative n is limited only by the capacity of the computer
+    being used.

 NAME
-    digits - return number of digits in an integer or integer part
+    digits - return number of "decimal" digits in an integral part
 
 SYNOPSIS
-    digits(x)
+    digits(x [,b])
 
 TYPES
     x		real
+    b		integer >= 2, defaults to 10
 
     return	integer
 
 DESCRIPTION
-    For real x, digits(x) returns the number of digits in the decimal
+    Returns number of digits in the standard base-b representation
-    representation of int(abs(x)).  If x >= 1, digits(x) = 1 + ilog10(x).
+    when x is truncated to an integer and the sign is ignored.
+
+    To be more precise: when abs(int(x)) > 0, this function returns
+    the value 1 + ilog(x, b).  When abs(int(x)) == 0, then this
+    function returns the value 1.
+
+    If omitted, b is assumed to be 10.  If given, b must be an
+    integer > 1.
+
+    One should remember these special cases:
+
+	digits(12.3456) == 2    computes with the integer part only
+	digits(-1234) == 4      computes with the absolute value only
+	digits(0) == 1          specical case
+	digits(-0.123) == 1     combination of all of the above
 
 EXAMPLE
-    > print digits(0), digits(0.0123), digits(3.7), digits(-27), digits(-99.7)

+    display - set and/or return decimal digits for displaying numbers
+
+SYNOPSIS
+    display([d])
+
+TYPES
+    d		integer >= 0
+
+    return	integer
+
+DESCRIPTION
+    When given an argument, this function sets the maximum number of
+    digits after the decimal point to be printed in real or exponential
+    mode in normal unformatted printing (print, strprint, fprint) or in
+    formatted printing (printf, strprintf, fprintf) when precision is
+    not specified.  The return value is the previous display digit value.
+
+    When given no arguments, this function returns the current
+    display digit value.
+
+    The builtin function:
+
+    	display(d)
+	display()
+
+    is an alias for:
+
+	config("display", d)
+	config("display")
+
+    The display digit value does not change the stored value of a number.
+    It only changes how a stored value is displayed.
+
+    Where rounding is necessary to display up to d decimal places,
+    the type of rounding to be used is controlled by config("outround").
+
+EXAMPLE
+    > print display(), 2/3
+    20 ~0.66666666666666666667
+
+    > print display(40), 2/3
+    20 ~0.6666666666666666666666666666666666666667
+
+    > print display(5), 2/3
+    40 ~0.66667
+
+LIMITS
+    d >= 0
