Class BoundMath

• ```public final class BoundMath
extends Object```
Java will sometimes return Math.NaN or Math.Infinity when numbers get to large or too small. This can have undesirable effects. This class provides some basic math functions that may be in danger of returning such a value. This class imposes a very large and small ceiling and floor to keep the numbers within range.
