How often do you spend your time then you switch your attention from your display to the desktop calculator to calculate some expressions what you need? Now you can save a lot of your precious seconds, if you'll become a user of The Calculator - a universal, powerful tool for scientific and engineering computations.

Usually this small program hides out in the System Tray and doesn't cower the space of your screen. But only press NumLock key and The Calculator will pop up to help you with your computations.

The Calculator - Scientific Engineering Calculator For Windows

The value suffixes is one of the most interesting features of The Calculator.

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.

It's simple, it's easy-to-use and it's effective!



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 the special file, and then used in your computations by name, just as 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
  • two types of the interface - full and ascetic
