Unix / Linux - Shell Builtin Mathematical Functions
本教程的大部分内容涵盖了 Bourne Shell，但此页面列出了 Korn Shell 可用的所有数学内置函数。
The most of the part of this tutorial covered Bourne Shell but this page list down all the mathematical builti-in functions available in Korn Shell.
Korn Shell 提供对标准数学函数集的访问权限。它们使用 C 函数调用语法进行调用。
The Korn shell provides access to the standard set of mathematical functions. They are called using C function call syntax.
