Detailed Description

Vector Math Helper Functions.

Math Helper Functions.

Helper functions for various mathematical operations. This header can be included in other libraries and projects to help deal with these sorts of issues. It is usually included by default in a library project. If you want to include this file into your own progs, you can include math.h from src/shared/.
