#36493 [Opn->Asn]: Unable to determine maximum floating point b

ID: 36493 Updated by: tony2001@php.net Reported By: terrafrost at gmail dot com -Status: Open +Status: Assigned Bug Type: Math related Operating System: Linux PHP Version: 4.4.2 -Assigned To: +Assigned To: tony2001 Previous Comments: ------------------------------------------------------------------------ [2006-02-23 07:11:16] terrafrost at gmail dot com Description: ------------ I've ran into some difficulty attempting to figure out what the maximum size of the exponent in floats is. Reproduce code: --------------- <? $x = 2; $y = 1; for ($bits=1; ($x*=2) > ($y*=2); $bits++); echo $bits; ?> Expected result: ---------------- Assuming php.net's statement about the 64-bit IEEE standard being the most common representation of float, I'd expect to get 1024 as the result. Actual result: -------------- On Windows, I do indeed get the correct result. On Linux, all I get are timeout errors. I've tried it with both PHP4 and PHP5 and get the same results for each. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=36493&edit=1
