tinymath

Tinymath is an effective math library, which is completely written as a C++ template, and can be easily used with other projects. Designed to be a lightweight, powerful, and flexible mathematical library, it was created to fill a gap in the market.

The foundation of tinymath is exceptionally compact, with only essential operations being implemented. If you require more functions than addition and multiplication, you can use another project that is based on tinymath. This makes it highly customizable and adaptable to fit any project's specific needs.

For instance, if you want to use geometrical functions for matrixes, you can use Tinygeo – a project that builds on top of the already highly functional Tinymath library. The flexibility of Tinymath means that you can easily expand your mathematical capabilities without having to seek out another software, making it an excellent addition to any project's toolbox.
