Wcalc is a very capable calculator. It supports abitrary precision, has standard functions (sin, asin, and sinh for example, in either radians or degrees), many pre-defined constants (pi, e, c, etc.), support for using variables, 'active' variables, a command history, hex/octal/binary input and output, unit conversions, embedded comments, and an expandable expression entry field. It evaluates expressions using the standard order of operations.

Wcalc uses intuitive expressions. For example, Wcalc will evaluate: 5sin 4!-7*2(4%6)^2 to be -221.96631678

Wcalc also comes in a command-line version that works on most (if not all) forms of Unix (including Linux and BSD). To support arbitrary precision, Wcalc relies on the GMP and MPFR libraries. In the MacOSX release, these are compiled-in, so there's no need for you to install them yourself.

What's New in This Release: [ read full changelog ]

· Sync preferences to disk predictably (when pref window closes)
· Fix display glitches when auto-resizing with extremely large numbers
· Add max-precision preference
· Overhaul simple calculator mode, remove crashes, made much more robust
· Accept input from a wcalc_input environment variable
· Make engineering notation command more reliable
· Add documentation for sinc and exp functions
· Made engineering notation a three-way toggle (auto/always/never)
· Accept @NaN@ (not-a-number) and @Inf@ (infinity) as input, which fixes some compound operations that would have incorrectly reported syntax errors.
· Fixed FORTRAN-style syntax errors
· Updated licensing to be GPLv2 compatible
