iota-calc looks like an ordinary scientific calculator - but looks can be deceiving, iota-calc is a revolution! Ordinary calculators just give you an answer, iota-calc will explain why it got the answer it did. With most calculators, if you mistype a number, you have to start all over, iota-calc lets you easily correct any mistakes. Most calculators cover up too much so that your can't see your work, iota-calc has a mini-calc mode, which gives it an uniquely small footprint, but is still fully useable. Plus your last answer shows in the dock and in the application switcher, so if iota-calc gets covered up by another window, you still see your last answer. Other calculators aren't easy to use, iota-calc shines here as well, we've provided a guided tour that will make you an expert very quickly. These are just a few of the reasons why we think iota-calc is special, but you don't need to take for it for it - you can take it for a test drive @ <http://solrobots.com/iotacalc/download.html>

Key Features:
- Supports a rich expression format, which is in most cases identical to what you would type in your programming language. Expression length is unlimited.
- Support for adding unlimited numbers of variables or variable expressions.
- Built-in debugger that lets you see the expression simplified step by step.
- Debugger Back-step lets you backup as many steps as you like so that you can replay critical operations.
- C/C++ operator precedence
- Mouse optional, all calculator commands and functions can be done using the keyboard alone.
- Mini-Calc Mode lets your calculator take up very little screen real estate, and yet remain entirely usable.
- Running paper tape(s) (1 per calculator) for calculations, allows annotations, and is stored between runs.
- Built-in Ascii chart makes it easy to look up even invisible characters.
- View results in big endian (default) or little endian.
- Numerous built-in unit conversions (memory sizes, lengths, areas, volumes, temperatures etc.)
