Whatever you're doing, the program’s flexibility is key. If you need more, you can store results in variables, define your own functions, use complex numbers, and perform all your calculations with up to 50 digits of precision. Again, double-click anything helpful and it’s entered into the expression area. These can be viewed and searched in a panel if you’re not sure what to enter, or you can start typing and allow the Autocomplete feature to show you any options (type "G", select Geomean - the geometric mean - and it’s entered for you).Ī built-in Formula book has a small number of expressions on offer: quadratic equations, the volume of a cone, area of a sphere, and so on. There are 80 built-in mathematical functions and 150 scientific constants ready for use. It doesn’t mind if you type "2+2" or "2+2=", you'll get the same answer as soon as you hit Enter. SpeedCrunch isn’t strict about its own syntax. Verdict:Īn excellent calculator with a lengthy list of powerful features, but is still easy enough for math novices to use.There’s an optional numeric keypad (View > Keypad) if you prefer clicking buttons to typing, although it'll probably just slow you down.

A built-in Formula Book has simple prebuilt items you can enter with a double-click (quadratic equations, volume of a cone, area of a cylinder), or you can insert more than 150 scientific constants with a click or two.Īll your calculations can be carried out with up to 50 digits of precision, with support for complex numbers, base and unit conversions, and more. SpeedCrunch does its best to help with your expressions, too. Click whatever you need and it's entered for you. For example, typing A gets you abs, absdev, ampere, and, angstrom, ans, arccos, arcosh (the expanded name is displayed after each one to help you identify it). Start to type a function name and autocomplete displays possible options. There are 80+ mathematical functions to explore, but these are also easier to use than you might expect. of 2 - SpeedCrunch - GUI Calculator - posted in Utilities: SpeedCrunch is a fast, high precision and powerful desktop calculator.Available for LinuxLinux, WindowsMicrosoft Windows, and Mac OS XMac OS X.Few of its distinctive features are: scrollable display up to 50 decimal precisions unlimited variable storage intelligent automatic completion full keyboard-friendly more.
