The Javadoc for FastMath says that it is a replacement for StrictMath, which is why I tested against that. But it's useful to test against Math as well. Note that a lot of Math methods actually delegate to StrictMath anyway. The main ones that don't are toRadians/toDegrees and min/max. By the way, I got different results in Eclipse and when using Java 1.5, so any conclusions we draw from the performance tests need to document the conditions. > > Regards, > Gilles > > --------------------------------------------------------------------- > To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org > For additional commands, e-mail: dev-h...@commons.apache.org > > --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@commons.apache.org For additional commands, e-mail: dev-h...@commons.apache.org
