An all purpose scientific calculator, designed with programmers in mind.

Key Features:
- Supports a rich expression format, which is in most cases identical to what you would type in your programming language.
- 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.)
- Built-in great circle route and straight line distance calculators.

Input/Output Formats:
- Input: Hexadecimal, Decimal, Binary, Octal, Boolean, and Characters (ASCII*).
- Output: Hexadecimal (32 bit integer, 32 and 64 bit floating point), Decimal, Binary, Octal, Boolean, Characters (ASCII*, UTF-8 and UTF-16), and Color (24 bit integer).
-Convert automatically between these types in your expression with the keyboard, a button, or a contextual menu.
*iota-calc gives you a super-set of ASCII, (For Macintosh we use Mac OS Roman and for Windows we use ISO Latin 1).
