Impulse Physics features its own, small math library in order to stay lean on dependencies.

Currently, it has support for the following:

• 2x2 Matrix
• 3x3 Matrix
• 4x4 Matrix
• 2D Vector
• 3D Vector
• 4D Vector

Floating-point numbers are almost always stored inaccurately in computers' memory. This is because of the |IEEE-754 standard that is used to store the number.

It also means that for example, 0.2 + 0.1 is not equal to 0.3; rather it is equal to 0.30000000000000004. Since computers are exact in comparison by default, you can see how you can run into issues with this.
