#44097 [Opn->Bgs]: error with match

ID: 44097 Updated by: johannes@php.net Reported By: cristian at buttasi dot it -Status: Open +Status: Bogus Bug Type: *Math Functions Operating System: Windows PHP Version: 5.2.5 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. .
