Following is the change from calc version 2.9.2 to 2.9.3t6:
WARNING: This patch is an unofficial alpha test patch by chongo@toad.com
(Landon Curt Noll) which as not been fully reviewed. Blame
chongo for any problems this patch may cause! The paranoid may
want to use 2.9.2 or wait for 2.9.4.
Calc can now compile on OSF/1, SGI and IBM RS6000 systems.
A number of systems that have both <varargs.h> and <stdarg.h> do
not correctly implement both types. On some System V, MIPS and DEC
systems, vsprintf() and <stdarg.h> do not mix. While calc will
pass the regression test, use of undefined variables will cause
problems. The Makefile has been modified to look for this problem
Added randmprime.cal which find a prime of the form h*2^n-1 >= 2^x
for some given x. The initial search points for 'h' and 'n'
are selected by a cryptographic pseudo-random generator.
The library script nextprim.cal is now a link to nextprime.cal.
The lib/Makefile will take care of this link and install.
The show command now takes singular forms. For example, the
command 'show builtin' does the same as 'show builtins'. This
allows show to match the historic singular names used in
Synced 'show builtin' output with 'help builtin' output.
Certain 64 bit processors such as the Alpha are now supported.
Added -once to the READ command. The command:
like the regular READ expect that it will ignore filename if
is has been previously read.
Improved the makefile. One now can select the compiler type. The
make dependency lines are now simple foo.o: bar.h lines. While
this makes for a longer list, it is easier to maintain and will
make future Makefile patches smaller. Added special options for
gcc version 1 & 2, and for cc on RS6000 systems.
Calc compiles cleanly under the watchful eye of gcc version 2.4.5
with the exception of warnings about 'aggregate has a partly
bracketed initializer'. (gcc v2 should allow you to disable
this type of warning with using -Wall)
Fixed a longjmp bug that clobbered a local variable in main().
Fixed a number of cases where local variables or malloced storage was
being used before being set.
Fixed a number of fence post errors resulting in reads or writes
just outside of malloced storage.
A certain parallel processor optimizer would give up on
code in cases where math_error() was called. The obscure
work-a-rounds involved initializing or making static, certain
The cryrand.cal library has been improved. Due to the way
the initial quadratic residues are selected, the random numbers
produced differ from previous versions.
The printing of a leading '~' on rounded values is now a config
option. By default, tilde is still printed. See help/config for
The builtin function base() may be used to set the output mode or
base. Calling base(16) is a convenient shorthand for typing
config("mode","hex"). See help/builtin.
The printing of a leading tab is now a config option. This does not
alter the format of functions such as print or printf. By default,
a tab is printed. See help/config for details.
The value atan2(0,0) now returns 0 value in conformance with
the 4.3BSD ANSI/IEEE 754-1985 math library.
For all values of x, x^0 yields 1. The major change here is
that 0^0 yields 1 instead of an error.
Fixed gcd() bug that caused gcd(2,3,1/2) to ignore the 1/2 arg.
Fixed ltol() rounding so that exact results are returned, similar
to the way sqrt() and hypot() round, when they exist.
The file help/full is now being built.
The man page is not installed by default. One may install either
the man page source or the cat (formatted man) page. See the
Added a quit binding. The file lib/bindings2 shows how this new
One can now do a 'make check' to run the calc regression test
within in the source tree.
The regression test code is now more extensive.
Updated the help/todo list. A BUGS file was added. Volunteers are
welcome to send in patches!
Following is the change from calc version 2.9.1 to 2.9.2:
Fixed floor() for values -1 < x < 0.
Fixed ceil() for values -1 < x < 0.
Fixed frac() for values < 0 so that int(x) + frac(x) == x.
Fixed wild fetch bug in zdiv, zquo and zmod code.
Fixed bug which caused regression test #719 to fail on some machines.
Added more regression test code.
Following is the change from calc version 2.9.0 to 2.9.1:
A major bug was fixed in subtracting two numbers when the first
number was zero. The problem caused wrong answers and core dumps.
Following is a list of visible changes to calc from version 1.27.0 to 2.9.0:
Full prototypes have been provided for all C functions, and are used
if calc is compiled with an ANSI compiler.
Newly defined variables are now initialized to the value of zero instead
of to the null value. The elements of new objects are also initialized
to the value of zero instead of null.
The gcd, lcm, and ismult functions now work for fractional values.
A major bug in the // division for fractions with a negative divisor
A major bug in the calculation of ln for small values was fixed.
A major bug in the calculation of the ln and power functions for complex
A major lack of precision for sin and tan for small values was fixed.
A major lack of precision for complex square roots was fixed.
The "static" keyword has been implemented for variables. So permanent
variables can be defined to have either file scope or function scope.
Initialization of variables during their declaration are now allowed.
This is most convenient for the initialization of static variables.
The matrix definition statement can now be used within a declaration
statement, to immediately define a variable as a matrix.
Initializations of the elements of matrices are now allowed. One-
dimensional matrices may have implicit bounds when initialization is
The obj definition statement can now be used within a declaration
statement, to immediately define a variable as an object.
Object definitions can be repeated as long as they are exactly the same
as the previous definition. This allows the rereading of files which
happen to define objects.
The integer, rational, and complex routines have been made into a
'libcalc.a' library so that they can be used in other programs besides
the calculator. The "math.h" include file has been split into three
include files: "zmath.h", "qmath.h", and "cmath.h".
Following is a list of visible changes to calc from version 1.26.4 to 1.27.0:
Added an assoc function to return a new type of value called an
association. Such values are indexed by one or more arbitrary values.
They are stored in a hash table for quick access.
Added a hash() function which accepts one or more values and returns
a quickly calculated small non-negative hash value for those values.
Following is a list of visible changes to calc from version 1.26.2 to 1.26.4:
Misc typo and working fixes to comments, help files and the man page.
Following is a list of visible changes to calc from version 1.24.7 to 1.26.2:
There is a new emacs-like command line editing and edit history
feature. The old history mechanism has been removed. The key
bindings for the new editing commands are slightly configurable
since they are read in from an initialization file. This file is
usually called /usr/lib/calc/bindings, but can be changed by the
CALCBINDINGS environment variable. All editing code is
self-contained in the new files hist.c and hist.h, which can be
easily extracted and used in other programs.
Two new library files have been added: chrem.cal and cryrand.cal.
The first of these solves the chinese remainder problem for a set
of modulos and remainders. The second of these implements several
very good random number generators for large numbers.
A small bug which allowed division by zero was fixed.
A major bug in the mattrans function was fixed.
A major bug in the acos function for negative arguments was fixed.
A major bug in the strprintf function when objects were being printed
A small bug in the library file regress.cal was fixed.
