Product Description:
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.
Examples:- 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's new in this version:
- Fixed an incompatibility of the Widget with MacOS 10.5 Leopard;
- Better handling of Service shortcut change.

emaNneercSCaution : 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.
Examples:

Here's "irb" in the Terminal:
irb(main):001:0> x = 7
=> 7
irb(main):002:0> 4 * x
=> 28
Here's RubyCalc:
>> x = 7
=> 7
>> 4 * x
=> -:1: undefined local variable or method `x' for main:Object (NameError)
See? RubyCalc doesn't remember variable values. So if I wanted to use Ruby as a calculator, why wouldn't I just use "irb" in the Terminal?
