The Calculator is small and handy. It supports compound expressions, bit operations, unlimited number of user variables and constants, and works with various types of notation.

Special features:

* User Variables. In computations, you can save your intermediate results in variables for further use. * User Constants. Some frequently used values, such as physical and mathematical constants, may be written in a special file, and then used in your computations by name, just like variables. The difference is, in fact, that you can't change a constant. * Value Suffixes. Very small or very large values (such as micrometers, megahertz, picofarads, etc.) are often used in engineering computations. For input simplification, we invented a system of value suffixes. A suffix is a letter, which is added to the number value and indicates that the calculator must multiply this value by the specific coefficient. * Simplified notation of expressions with parentheses. When multiplying by an expression within parentheses, you may omit the "*" symbol. * Last input string memorizing * Hot key call. When The Calculator is running, press the Num Lock key to hide or show the main program window. * Autorun * Size, font and color setup
