#36356 [Bgs]: After form submit system changing value other then entered

ID: 36356 Updated by: derick@php.net Reported By: Vlad at valuead dot com Status: Bogus Bug Type: *Math Functions Operating System: Gentoo PHP Version: 4.4.2 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. .
