RubyCalc: an application, a service and a widget
Version: 1.0.4RubyCalc is the best solution if you need a quick, light, and free calculator able to:
Operating System: Mac OS X
· use numbers arbitrarily long (more than 10 figures...) ?
· type long expressions with parenthesis but without mistake ?
· easily mix numbers in different basis (binary, decimal, hexadecimal...) ?
RubyCalc may be what you are looking for. It supplies an application with its service, and a widget.
