Fast transcendent / trigonometric functions for Java

Question

Since the trigonometric functions in java.lang.Math are quite slow: is there a library that does a quick and good approximation? It seems possible to do a calculation severa

Answer 1

On the x86 the java.lang.Math sin and cos functions do not directly call the hardware functions because Intel didn't always do such a good job implimenting them. There is a nice explanation in bug #4857011.

You might want to think hard about an inexact result. It's amusing how often I spend time finding this in others code.
