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 and implicit multiplication. For example, Wcalc will evaluate:
5sin 4!-7*2(4%6)^2 to be
-221.96631678. Wcalc will also more...
