Note Submitter: codiemorgan at gmail.com ---- Correction for "russell dot harper at springboardnetworks dot com". 0.0 does return false, because 0.0 = 0. the reason you are getting a TRUE from your value is because your are putting 0.0 inside a string. yours: print '0.0'."\t".((bool)'0.0'? 1: 0)."\n"; try: print 0.0."\t".((bool)0.0? 1: 0)."\n"; "0.0" => true; Because it is a non empty string. '0.0' => true; Because it is a non empty string. 0.0 => false; because it is a value equal to 0. for "" = false while "0.0" and "200" = true;
