pmaCalc

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.
