Math (JOML 1.9.18 API)

java.lang.Object
- org.joml.Math

```
public class Math
extends Object
```
Contains fast approximations of some Math operations.
By default, Math methods will be used by all other JOML classes. In order to use the approximations in this class, start the JVM with the parameter -Djoml.fastmath.
There are two algorithms for approximating sin/cos:
1. arithmetic polynomial approximation contributed by roquendm
2. theagentd's linear interpolation variant of Riven's algorithm from http://www.java-gaming.org/
By default, the first algorithm is being used. In order to use the second one, start the JVM with -Djoml.sinLookup. The lookup table bit length of the second algorithm can also be adjusted for improved accuracy via -Djoml.sinLookup.bits=<n>, where <n> is the number of bits of the lookup table.
