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

The java.lang.Math functions call the hardware functions. There should be simple appromiations you can make but they won't be as accurate.
