Description: ------------ Linux version 2.6.22-3-686 (Debian 2.6.22-6) ([EMAIL PROTECTED]) (gcc version 4.1.3 20071019 (prerelease) (Debian 4.1.2-17)) #1 SMP Mon Nov 12 08:32:57 UTC 2007 PHP (PHP 5.2.5-2 with Suhosin-Patch 0.9.6.2 (cli) (built: Feb 1 2008 21:17:20)) returns a rather strange result for a certain mathematical expression. Also, the weird result is only returned in very specific cases: php> = (0.005 + 0.002/3 + 0.194 + 0.001/3 )/2 0.0: (notice the semicolon!) php> = (0.004 + 0.002/3 + 0.195 + 0.001/3 )/2 0.1 php> = (0.005 + 0.194 + 0.002/3 + 0.001/3 )/2 0.1 When $result is the 'strange' result: is_float($result) == true is_float(0.0:) ==> syntax error Needless to say the strange result is resulting in syntax-errors in the code where it occurs.
