#42581 [Opn->Bgs]: strange echo of float vals

ID: 42581 Updated by: derick@php.net Reported By: ger dot kirill at gmail dot com -Status: Open +Status: Bogus Bug Type: Math related Operating System: Windows, Linux PHP Version: 5.2.4 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. .
