Full description
Wcalc is a very capable calculator. It 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.
