SpeedCrunch is an open source, cross platform calculator designed for power users who struggle with formulas like volume of sphere and surface area of a cone. SpeedCrunch’s built in help system containing mathematical formulas, physical constants and functions ensures that you arrive at the correct result each time you hit Enter without having to memorize any 18 digit number.
SpeedCrunch has a Math book with a few basic formulas to calculate volume, area and other dimensions of different 3D and 2D objects. It also has quadratic equation formulas, but Trigonometric formulas are sorely missing. When you click on a formula, it immediately appears on the calculator input box. Now you just have to replace the variables with your figures and press the Enter key.
Similarly, there are lists of various mathematical and physical constants categorized by subject – astronomy, atomic & nuclear, electromagnetic, physico-chemical and general physics.
The built-in functions let you calculate things like average, binomial distribution mean, permutation etc by just keying in the numbers.
But functionality wise, SpeedCrunch is still way behind Windows 7’s calculator. Windows 7’s calculator offers different calculator modes – scientific, programmer, statistics – a flexibility that SpeedCrunch cannot match. The only mode SpeedCrunch has is scientific and even that is limited if you do a key-by-key comparison. For instance, there is no inverse (1/x), x2, x3, ˟√y and a number of other inputs that are frequently required in calculations.
SpeedCrunch’s saving grace are it’s tertiary features like syntax highlighting, auto completion, auto correction, history and session saver.
SpeedCrunch is available for Windows, Mac and all major Linux distributions.
