Unix / Linux - Shell Builtin Mathematical Functions
The most of the part of this tutorial covered Bourne Shell but this page pst down all the mathematical builti-in functions available in Korn Shell.
The Korn shell provides access to the standard set of mathematical functions. They are called using C function call syntax.
