Good catch, for example: Name StrictMath FastMath Math sin 128 1.0 238 1.8512 85 0.6620 <= current sin 1331 1.0 601 0.4518 1365 1.0260 <= 0 -> 10000000 There are probably quite a few other tests that exhibit the same problem. > > --------------------------------------------------------------------- > 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
