The JSMATH CLI is a simple command-line interface written in javascript that provides javascript math functions to the command line and to bash scripting
To use the JSMATH CLI, first install the library globally on your system (if you get a permission error, use sudo)
$ npm install jsmath-cli --global
Now, you can use all the following math functions like so (used in a bash script for reference), along with explanations for the functions and the output for the examples
