All-purpose scientific calculator, designed for programmers

Key Features:
- Supports rich expression formats, identical to what you might type in your programming language
- Support for adding unlimited numbers of variables/expressions
- Built-in debugger, lets you see the expression simplified step by step
- Debugger Back-step lets you backup as many steps as you like
- C/C++ operator precedence
- Mouse optional, all calculator commands and functions can be done using the keyboard
- Mini-Calc Mode lets your calculator take up very little screen real estate
- 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 (default) or little endian
- Numerous built-in unit conversions (memory sizes, lengths, areas, volumes, temperatures etc.)
- Built-in great circle 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, (Mac=Mac OS Roman / Win=ISO Latin 1)
