Post #72,882 by admin 1/6/03 10:12:59 AM Reply	Doesn't seem to make any difference. Another oddity: double y = 0.0; y = pow(10.0, 3); if ((123456 / y) == (123456 / 7)) { printf("works\\n"); } prints 'works'. Regards, -scott anderson "Welcome to Rivendell, Mr. Anderson..."

Oh - to discover a real compiler problem - (deSitter) - (1) - Jan. 6, 2003, 09:36:04 PM EST

This is not considered a compiler problem by the GCC folks. - (admin) - Jan. 6, 2003, 10:18:20 PM EST

Scott, that's a bug worthy of catching - (Simon_Jester) - (1) - Jan. 6, 2003, 10:34:21 PM EST
