lua-math-extension-module

A lua module including functions meant to extend the math library Note: Uses at least Lua 5.3

How to add to Lua:

1. Move the file into your LUA_PATH
2. Just use require "mathext" to have your Lua files be able to use the functions defined in the module.

A list of the functions defined here:

• round(x) Takes a float value and rounds it to the nearest integer
• fact(x) Takes an int value and returns the factorial of it
• perm(n, r) Takes two int values, n being larger than r, and returns the permutation of the two of them
• comb(n, r) Does the same as perm, but returns the combination of the two values

Here is an example of using the module in your lua programs:

mathext = require "mathext"

local num = 67.8
print(mathext.round(num))    --> 68
