ID: 48455 Updated by: ras...@php.net Reported By: aldo at totalaldo dot com -Status: Open +Status: Bogus Bug Type: Strings related Operating System: FreeBSD 7.2-RELEASE PHP Version: 5.2.9 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.
