SpeedCrunch is a free, high-precision scientific calculator for Windows, Linux and Mac OS. Apart from basic mathematical operations (addition, subtraction, multiplication or division), the application offers a set of slightly more advanced tools aimed at more demanding recipients. SpeedCrunch enables the calculation of trigonometric functions, the calculation of elements, the storage of results in variables, and offers more than 80 built-in mathematical functions - with the ability to define your own.

The calculator allows you to perform calculations with an accuracy of up to 50 digits, and its operation is done via a keyboard (an optional on-screen keyboard is available). SpeedCrunch allows you to store all kinds of calculations in a history that can be viewed at any time. The application offers access to the most popular set of constants, supports bitfields and enables decimal, binary, octal and hexadecimal operation.
