Wcalc is a very capable calculator. It supports abitrary precision, hasstandard functions (sin, asin, and sinh for example, in either radiansor degrees), many pre-defined constants (pi, e, c, etc.), support forusing variables, "active" variables, a command history, hex/octal/binaryinput and output, unit conversions, embedded comments, and an expandableexpression entry field. It evaluates expressions using the standardorder of operations. Wcalc uses intuitive expressions. For example, Wcalc will evaluate: 5sin 4!-7*2(4%6)^2 to be -221.96631678
