+The following are the changes from calc version 2.12.6.1 to date:
+
+    Improved gen_v1(h,n) in lucas.cal to use an even faster search method.
+
+    Improved are checking in lucas.cal.  In particular both h and n must be
+    integers >= 1.  In the case of both rodseth_xhn(x, h, n) and gen_v1(h, n)
+    h must be odd.
+
+    Fixed an C code intending issue that was reported by Thomas Walter
+    <th dot walter42 at gmx dot de> in zfunc.c.
+
+
+The following are the changes from calc version 2.12.6.0 to 2.12.6.0:
+
+    Added the makefile variable ${COMMON_ADD} that will add flags
+    to all compile and link commands. The ${COMMON_ADD} flags are
+    appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}.  This
+    facility is available to nearly all platforms except those with
+    very old make commands that do not understand the += operator.
+
+    Example on macOS (Darwin), one may invoke clang's -fsanitize
+    facility by:
+
+	make clobber all \
+	  COMMON_ADD='-fsanitize=undefined -fsanitize=address'
+
+    Another example.  To force C warnings to be treated as errors:
+
+	make COMMON_ADD='-Werror'
+
+    Created a GitHub repository for calc:
+
+	https://github.com/lcn2/calc
+
+    NOTE: The calc GitHub repository represents the an active
+	  development stream.  While an effort will be made to keep
+	  the master branch of the calc GitHub repository in working
+	  order, that tree may be unstable.  Those wishing for more
+	  reliable releases use releases found at calc mirror sites:
+
+	    http://www.isthe.com/chongo/tech/comp/calc/calc-mirror.html
+
+    IMPORTANT NOTE:
+
+	On 2017 June 05, the calc GitHub history was re-written.
+	Anyone who was tracking the calc "pre-release" on GitHub prior
+	to version 2.12.6.0 should do a:
+
+	    git reset --hard origin/master
+	    git cleanup -f
+
+	Or you may just want to start over:
+
+	    rm -rf calc
+	    git clone https://github.com/lcn2/calc.git
+
+	Sorry about that.  The previous GitHub repository was an useful
+	experiment.  Based on what we learned, we decided to rebuild it.
+
+    Renamed README to README.FIRST.  Added README.md for the
+    GitHub repository.
+
+    Fixed reading from standard input (stdin) when -p is given on
+    the command line.  This now prints hello:
+
+	echo hello | calc -p 'stdin = files(0); print fgetline(stdin);'
+
+    Added more debugging related to stdin when bit 4 of calc_debug
+    is set (e.g., running calc with -D16).
+
+    Updated the calc(1) man page and 'help file' to explain about
+    reading from standard input (stdin).
+
+    Added some clarifying remarks for 'help ptest' explaining that
+    the ptest builtin can return 1 is some cases where the test
+    value is a pseudoprime.
+
+    Removed duplicate copyright comments from the help/builtin that
+    is built.
+

+# What is calc?
+
+Calc is an interactive calculator which provides for easy large
+Otherwise, it enters interactive mode.  In this mode, it accepts
+commands one at a time, processes them, and displays the answers.
+In the simplest case, commands are simply expressions which are
+evaluated.  For example, the following line can be input:
+
+```sh
+3 * (4 + 1)
+```
+
+and the calculator will print:
+
+```sh
+15
+```
+
+Calc as the usual collection of arithmetic operators +, -, /, * as
+well as ^ (exponentiation), % (modulus) and // (integer divide).
+For example:
+
+```sh
+3 * 19^43 - 1
+```
+
+will produce:
+
+```sh
+29075426613099201338473141505176993450849249622191102976
+```
+
+Notice that calc values can be very large.  For example:
+
+```sh
+2^23209-1
+```
+
+will print:
+
+```sh
+402874115778988778181873329071 ... many digits ... 3779264511
+```
+
+The special '.' symbol (called dot), represents the result of the
+last command expression, if any.  This is of great use when a series
+of partial results are calculated, or when the output mode is changed
+and the last result needs to be redisplayed.  For example, the above
+result can be modified by typing:
+
+```sh
+. % (2^127-1)
+```
+
+and the calculator will print:
+
+```sh
+47385033654019111249345128555354223304
+```
+
+For more complex calculations, variables can be used to save the
+intermediate results.  For example, the result of adding 7 to the
+previous result can be saved by typing:
+
+```sh
+curds = 15
+whey = 7 + 2*curds
+```
+
+Functions can be used in expressions.  There are a great number of
+pre-defined functions.  For example, the following will calculate
+the factorial of the value of 'whey':
+
+```sh
+fact(whey)
+```
+
+and the calculator prints:
+
+```sh
+13763753091226345046315979581580902400000000
+```
+
+The calculator also knows about complex numbers, so that typing:
+
+```sh
+(2+3i) * (4-3i)
+cos(.)
+```
+
+will print:
+
+```sh
+17+6i
+-55.50474777265624667147+193.9265235748927986537i
+```
+
+The calculator can calculate transcendental functions, and accept and
+display numbers in real or exponential format. For example, typing:
+
+```sh
+config("display", 70),
+epsilon(1e-70),
+sin(1)
+```
+
+prints:
+
+```sh
+0.8414709848078965066525023216302989996225630607983710656727517099919104
+```
+
+Calc can output values in terms of fractions, octal or hexadecimal.
+For example:
+
+```sh
+config("mode", "fraction"),
+(17/19)^23
+print
+base(16),
+(19/17)^29
+print
+log(79.3i)
+```
+
+ will print:
+
+```sh
+19967568900859523802559065713/257829627945307727248226067259
+
+0x9201e65bdbb801eaf403f657efcf863/0x5cd2e2a01291ffd73bee6aa7dcf7d1
+
+0x17b5164ac24ee836bf/0xc7b7a8e3ef5fcf752+0x883eaf5adadd26be3/0xc7b7a8e3ef5fcf752i
+```
+
+All numbers are represented as fractions with arbitrarily large
+numerators and denominators which are always reduced to lowest terms.
+Real or exponential format numbers can be input and are converted
+to the equivalent fraction.  Hex, binary, or octal numbers can be
+input by using numbers with leading '0x', '0b' or '0' characters.
+Complex numbers can be input using a trailing 'i', as in '2+3i'.
+Strings and characters are input by using single or double quotes.
+
+Commands are statements in a C-like language, where each input
+line is treated as the body of a procedure.  Thus the command
+line can contain variable declarations, expressions, labels,
+conditional tests, and loops.  Assignments to any variable name
+will automatically define that name as a global variable.  The
+other important thing to know is that all non-assignment expressions
+which are evaluated are automatically printed.  Thus, you can evaluate
+an expression's value by simply typing it in.
+
+Many useful built-in mathematical functions are available.  Use the:
+
+```sh
+help builtin
+```
+
+command to list them.
+
+You can also define your own functions by using the 'define' keyword,
+followed by a function declaration very similar to C.
+
+```sh
+define f2(n)
+{
+	local ans;
+
+	ans = 1;
+	while (n > 1)
+		ans *= (n -= 2);
+	return ans;
+}
+```
+
+Thus the input:
+
+```sh
+f2(79)
+```
+
+will produce:
+
+```sh
+1009847364737869270905302433221592504062302663202724609375
+```
+
+Functions which only need to return a simple expression can be defined
+using an equals sign, as in the example:
+
+```sh
+define sc(a,b) = a^3 + b^3
+```
+
+Thus the input:
+
+```sh
+sc(31, 61)
+```
+
+will produce:
+
+```sh
+256772
+```
+
+Variables in functions can be defined as either 'global', 'local',
+or 'static'.  Global variables are common to all functions and the
+command line, whereas local variables are unique to each function
+level, and are destroyed when the function returns.  Static variables
+are scoped within single input files, or within functions, and are
+never destroyed.  Variables are not typed at definition time, but
+dynamically change as they are used.
+
+For more information about the calc language and features, try:
+
+```sh
+help overview
+```
+
+Calc has a help command that will produce information about
+every builtin function, command as well as a number of other
+aspects of calc usage.  Try the command:
+
+```sh
+help help
+```
+
+for and overview of the help system.  The command:
+
+```sh
+help builtin
+```
+
+provides information on built-in mathematical functions, whereas:
+
+```sh
+help asinh
+```
+
+will provides information a specific function.  The following
+help files:
+
+```sh
+help command
+help define
+help operator
+help statement
+help variable
+```
+
+provide a good overview of the calc language.  If you are familiar
+with C, you should also try:
+
+```sh
+help unexpected
+```
+
+It contains information about differences between C and calc
+that may surprize C programmers.

Anyone who was tracking the calc "pre-release" on GitHub prior to version 2.12.6.0 should do a: git reset --hard origin/master git cleanup -f Or you may just want to start over: rm -rf calc git clone https://github.com/lcn2/calc.git Sorry about that. The previous GitHub repository was an useful experiment. Based on what we learned, we decided to rebuild it.	2017-06-05 17:20:26 -07:00

Landon Curt Noll	62bdba6d22	Undo always enabling clang sanitize We are not ready, just yet, to enable: -fsanitize=undefined -fsanitize=address Instead we need to test with: make clobber all check COMMON_ADD='-fsanitize=undefined -fsanitize=address' Once the regression test passes, we can consider how to use COMMON_ADD during development.	2017-05-23 02:18:51 -07:00
Landon Curt Noll	4d9511243c	Prepare for version 2.12.6.0	2017-05-23 02:16:52 -07:00
Landon Curt Noll	188fd372ea	Added COMMON_ADD Makefile facility Added the makefile variable ${COMMON_ADD} that will add flags to all compile and link commands. The ${COMMON_ADD} flags are appended to both ${COMMON_CFLAGS} and ${COMMON_LDFLAGS}. This facility is available to nearly all platforms except those with very old make comamnds that do not understand the += operator.

Landon Curt Noll	beb13bf89f	Ignore source tarball files that are built The source tarballs that are released are built from development trees. A number of files are created that are not in the development tee. Other files development files are replaced. We also ignore all binary files and library files that are built.	2017-05-23 01:39:43 -07:00
Landon Curt Noll	a31078bbec	Remove all RCS @(#) lines and RCS strings Some folks might think: “you still use RCS”?!? And we will say, hey, at least we switched from SCCS to RCS back in … I think it was around 1994 ... at least we are keeping up! :-) :-) :-) Logs say that SCCS version 18 became RCS version 19 on 1994 March 18. RCS served us well. But now it is time to move on. And so we are switching to git. Calc releases produce a lot of file changes. In the 125 releases of calc since 1996, when I started managing calc releases, there have been 15473 file mods!	2017-05-23 01:33:23 -07:00
Landon Curt Noll	7ae4f4009c	Convert tarball tree to development tree calc GitHub philosophy All of the previous commits in the master branch are the consists of compressed source tarballs. The 125 git tags represent calc releases from version 2.10.2t30 (Sat Jul 06 1996 04:17:00 GMT-0700) to version 2.12.5.6 (Sun May 21 2017 15:03:29 GMT-0700). At this point master branch will switch from those released tarballs to the development tree. While we will make an effort to verify that commits won't break calc: sometimes we will end up breaking calc. You should consider the top of the master branch as potentially unstable. When we are ready to release calc, we will tag the commit with the calc version and submit a release on GitHub. The GitHub release will contain the usual RPMs, SRPMs, a release README and a released source tarball.	2017-05-22 23:32:12 -07:00
