pmaCalc 6.1 - pmaCalc is a expression Calculator

pmaCalc combines a scientific calculator, binary arithmetik
for programmers, and unit converter in an interesting package.

In addition to a fair range of scientific functions, it has
an unusual numeric stack, and a binary mode that
supports decimal, hexadecimal, octal, and binary arithmetic,
with a full complement of logical operators and bit manipulation
instructions. It has7 lines: hex, oct, dec, bin, ascii, 2's compl.
and roman. Each line is clickable for new data input. The others
immediately reflect that data input in their respective bases.

You can enter expressions by pressing buttons or
by typing them in (it's advisable to take care with the
syntax), and the stack offers a flexible alternative to the usual
memory functions. You can use fixed, floating and sci. point modes.

Other features include a Euro converter that handles all European Union
currencies, 150+ Units and 500+ Convertions.
