RubyCalc

Google can be used as a calculator really handier than the Calculator application of MacOS X.
But what if you are not connected to the Internet? Did you already need a quick, light, and free calculator able to :

• 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.

Caution : Rubycalc is using the Ruby language to perform the computations. The Ruby language have some specificities that you should be aware of, otherwise you may not understand the results.

• Integer divisions : 5/2 = 2 (remaining 1 = 5%2); but 5/2.0 = 2.5
• Power : 5^2 = 7 (binary exclusive OR operation) but 5**2 = 25 (power)

Please refere to a Ruby documentation if you have any doubt.

What is new in this release:

• Fixed an incompatibility of the Widget with MacOS 10.5 Leopard;
• Better handling of Service shortcut change.

Requirements:

MacOS 10.3.9 (10.4.3 for the widget)
