# Category:Wren-math

**Library**

This is an example of a library. You may see a list of other libraries used on Rosetta Code at Category:Solutions by Library.

**Wren-math** is a module which supplements the methods in the Wren programming language's Num and Bool classes. It consists of static methods organized into 4 classes: Math, Int, Nums and Boolean. Int and Nums contain methods specific to integer and number sequences respectively. Boolean enables bitwise operations to be performed on boolean values.

It is the fourth in a series of modules (listed on the language's [main page]) designed to assist with writing Rosetta Code tasks so the same code does not have to be written or copy/pasted time and time again thereby bloating a task's script code unnecessarily.

To use it all you need to do is to copy the source code (in the [talk page]) to a text file called *math.wren* and place this in the same directory as the importing script so the command line interpreter can find it.
