Small and handy calculator which supports compound expressions - Windows Freeware. 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. * 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. So, if you need to enter a 4 000 000, just type 4M. That's all! Need to calculate the cosine of 20 degrees? (By default, The Calculator works with radians) Type cos(20g) and get the result. * 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. * 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
