#40178 [Bgs]: Differents systems return differents values

ID: 40178 User updated by: bpita at netcombbs dot com Reported By: bpita at netcombbs dot com Status: Bogus Bug Type: *Network Functions Operating System: Win32, Linux32 and Linux64 PHP Version: 5.2.0 New Comment: Thanks, for your answer, I try to understand... but I use an internal function of php that returns differents values depends of my processor architecture ? It's correct ? Not should be the same and Php be in charge of this and return alway the same value independently of the 32b or 64b processor ? Thanks, Bernardo. Previous Comments: ------------------------------------------------------------------------ [2007-01-20 02:15:55] pajoye@php.net (bogus means "Not a bug" here) This is the internal representation of signed integer using unsigned integer. 32bits use one bit for the sign, that explains the negative _displayed_ values, but the internal values are the same. Big numbers should be processed using bcmath or pecl/big_int ------------------------------------------------------------------------ [2007-01-20 00:50:32] bpita at netcombbs dot com Description: ------------ Hi, I use this code in differents operating systems and plataforms (intel and amd) and return differents results.
