If, due to the way you computed the input value, none of them are significant to you, then that's your problem. sin() and cos() are still required to return the correct result assuming all bits of input are significant. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
