What makes SpeedCrunch differ from other traditional calculators : -

color the expression : - SpeedCrunch can always color the expression according to the syntax. You can easily distinguish numbers from variables. You can also see the matched parentheses.

automatic completion :- Type the letter c only and in less than a second you will be automagically given with choices of cos, cosh or your variables whose name start with c.

50 decimals at your disposal :- With its unique calculation routines, you can get up to 50 decimals of precision. Normally, all the important digits are shown, but you can also ask SpeedCrunch to round it to several digits.

precision :- When your calculation is quite complex and involving a chain of operations, this high precision ensures that you would get less rounding error in the end.

Calculation history :- Just press up and down arrow to access the expression which you typed before. Expression history of maximum last 100 expressions is saved between sessions.

Smart correction :- SpeedCrunch can still understand an incomplete expression. For example, just typing sin followed by Enter – likely means taking the sine of last value – is automatically translated as sin(ans).

parentheses :- Closing parenthesis can be left to SpeedCrunch, e.g. cos(pi/4 is automatically corrected to cos(pi/4).

Installation :-

For Ubuntu, Debian, Kubuntu, install it using the command below.
