Wcalc is a very capable calculator. It has standard functions (sin, asin, and sinh for example), many pre-defined constants (pi, e, c, etc.), support for using variables, a command history, hex/octal/binary input and output, unit conversions, bit-shifting, embedded comments, and an expandable expression entry field. It evaluates expressions using the standard order of operations.License: GNU General Public License (GPL)Changes:
Several display glitches with auto-resizing forlarge numbers have been fixed, as has thesimple-calc mode. Engineering notation andnon-number input (such as @NaN@ and @Inf@) havebeen made more reliable, as have some multi-stepoperations. The licensing has also been updated tobe GPLv2+ compatible.
