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.
