#41808 [Opn->Bgs]: number_format rounding error

ID: 41808 Updated by: tony2001@php.net Reported By: bunb at gmx dot de -Status: Open +Status: Bogus Bug Type: *General Issues Operating System: windows PHP Version: 4.4.7 New Comment: Floating point values have a limited precision. Hence a value might not have the same string representation after any processing. That also includes writing a floating point value in your script and directly printing it without any mathematical operations. If you would like to know more about "floats" and what IEEE 754 is read this: http://docs.sun.com/source/806-3568/ncg_goldberg.html Thank you for your interest in PHP.
