The following are the changes from calc version 2.11.0t10 to date:
|
||||
|
||||
Placed calc under version 2.1 of the GNU Lesser General Public License.
|
||||
|
||||
The calc commands:
|
||||
|
||||
help copyright
|
||||
help copying
|
||||
help copying-lgpl
|
||||
|
||||
should display the generic calc copyright as well as the contents
|
||||
of the COPYING and COPYING-LGPL files.
|
||||
|
||||
Those files contain information about the calc's GNU Lesser General
|
||||
Public License, and in particular the conditions under which you
|
||||
are allowed to change it and/or distribute copies of it.
|
||||
|
||||
Removed the lint facility from the Makefile. Eliminated Makefile
|
||||
variables: ${LCFLAGS}, ${LINT}, ${LINTLIB} and ${LINTFLAGS}.
|
||||
Removed the lint.sed file.
|
||||
|
||||
Cleaned up help display system. Help file lines that begin with
|
||||
'##' are not displayed.
|
||||
|
||||
Calc source and documentation now uses the the these terms:
|
||||
|
||||
*.cal files calc resource file
|
||||
*.a files calc binary link library
|
||||
#! files calc shell script
|
||||
|
||||
Renamed 'help stdlib' to 'help resource'. The 'help stdlib' is
|
||||
aliased to 'help resource' for ard compatibility.
|
||||
|
||||
Renamed config("lib_debug") to config("resource_debug").
|
||||
The config("lib_debug") will have the same effect as
|
||||
config("resource_debug") for backward compatibility.
|
||||
|
||||
Renamed the source sub-directory lib to cal. The default $CALCPATH
|
||||
now uses ./cal:~/cal (instead of ./lib:~/lib). Changed LIB_PASSDOWN
|
||||
Makefile variable to CAL_PASSDOWN.
|
||||
|
||||
Fixed misc compile warnings and bugs.
|
||||
|
||||
Fixed problem of incorrect paths in the formation of installed
|
||||
calc shell scripts.

|
||||
Fixed the make depend rule.
|
||||
|
||||
Applied Ernest Bowen's <ernie@turing.une.edu.au> complex function
|
||||
power(), exp() and transcendental function patch:
|
||||
|
||||
Calc will return a "too-large argument" error-value for exp(x,
|
||||
epsilon) if re(x) >= 2^30 or if an estimate indicates that the
|
||||
result will have absolute value greater than 2^2^30 * epsilon.
|
||||
Otherwise the evaluation will be attempted but may fail due to
|
||||
shortage of memory or may require a long runtime if the result
|
||||
will be very large.
|
||||
|
||||
The power(a, b, epsilon) builtin will return a "too-large result"
|
||||
if an estimate indicates that the result will have absolute value
|
||||
> 2^2^30 * epsilon. Otherwise the evaluation will be attempted
|
||||
but may fail due to shortage of memory or may require a long
|
||||
runtime if the result will be very large.
|
||||
|
||||
Changes have been made to the algorithms used for some special
|
||||
functions sinh(), cosh(), tanh(), sin(), cos(), etc., that make
|
||||
use of exp(). In particular tanh(x) is now much faster and
|
||||
doesn't run out of memory when x is very large - the value to
|
||||
be returned is then 1 to a high degree of accuracy.
|
||||
|
||||
When the true value of a transcendental function is 1, as is
|
||||
cos(x) for x == 0, calc's version of the function will now return
|
||||
1 rather than the nearest multiple of epsilon. E.g. cos(0, 3/8)
|
||||
no longer returns 9/8.
|
||||
|
||||
The restriction of abs(n) < 1000000 on scale(x, n) has been
|
||||
removed. The only condition n now has to satisfy for calc to
|
||||
attempt the operation is n < 2^31, the same as for calc to
|
||||
attempt x << n and x^n.
|
||||
|
||||
Changed root(x,n) so that when x is negative and n is odd it
|
||||
returns the principal complex n-th root of x rather than -1, e.g.
|
||||
root(-1,3) now returns -.5+.8660...i.
|
||||
|
||||
Changed power(a,b) to permit a to be negative when b is real.
|
||||
E.g. power(-2,3) will now return 8 rather than cause a "negative
|
||||
base" error.
|
||||
|
||||
Fixed several improper free and link problems in the comfunc.c code.
|
||||
|
||||
Removed BOOL_B64 symbol from Makefile.
|
||||
|
||||
The following config values return "true" or "false" strings:
|
||||
|
||||
tilde tab leadzero fullzero blkverbose verbose_quit
|
||||
|
||||
These config values can still be set with same boolean strings
|
||||
("on", "off", "true", "false", "t", ...) as well as via the
|
||||
numerical values 0 (for "false") and non-0 (for "true"), however.
|
||||
|
||||
Added -s to the calc command line. The -s flag will cause unused
|
||||
args (args after all of the -options on the command line) to remain
|
||||
as unevaluated strings.
|
||||
|
||||
If calc is called with -s, then the new function argv() will return
|
||||
the number of strings on the command line. Also argv(n) will return
|
||||
the n-th such string or null is no such string exists.
|
||||
|
||||
Calc now handles calc shell scripts. A calc shell script is an
|
||||
executable file that starts with:
|
||||
|
||||
#!/usr/local/bin/calc -S
|
||||
|
||||
Where ``/usr/local/bin/calc'' is the path to the calc binary.
|
||||
Additional -options may be added to the line, but it MUST
|
||||
start with -S. For example, the the executable file ``plus''
|
||||
contain the following:
|
||||
|
||||
#!/usr/local/bin/calc -S -e
|
||||
/*
|
||||
* This is a simple calc shell script to add two values
|
||||
*/
|
||||
print eval(argv(0)) + eval(argv(1));
|
||||
|
||||
then the following command:
|
||||
|
||||
./plus 23 'pi(1e-5)'
|
||||
|
||||
will print:
|
||||
|
||||
26.14159
|
||||
|
||||
If calc is called with -S as the first arg, then calc will assume that
|
||||
it is being called from a #! calc shell script file. The -S implies
|
||||
the -s flag. If -i is not given, -S also implies -d and -p.
|
||||
|
||||
Fixed the problem with non-literal string type checking for the
|
||||
C printf-like functions. Able to determine if "%ld" or "%lld"
|
||||
is appropriate for printing of 64 bit long longs by way of the C
|
||||
symbol L64_FORMAT in the longlong.h header file.
|
||||
|
||||
The following lines are treated as comments by calc:
|
||||
|
||||
#! this is a comment
|
||||
# this is a comment
|
||||
# this is a comment
|
||||
#
|
||||
# The lone # above was also a comment
|
||||
|
||||
Improved how calc makes changes to file descriptor interactive state.
|
||||
Moved state changing code to calc_tty() and orig_tty() in lib_calc.c.
|
||||
The libcalc_call_me_last() function will restore all changed descriptor
|
||||
states that have not already been restored.
|
||||
|
||||
Added the following read-only config values:
|
||||
|

config("program") path to calc program or calc shell script

config("basename") basename of config("program")

config("version") calc version string
