#47304 [Fbk]: typecast of numeric string to float produces strange result

ID: 47304 Updated by: pajoye@php.net Reported By: lennartvdd at mailordersolutions dot nl Status: Feedback Bug Type: Scripting Engine problem Operating System: Server 2003 for SBS SP2 - IIS PHP Version: 5.2.8 Assigned To: pajoye New Comment: What is the exact version of 2003, which processor do you use? However it works for me with the US locale on XP SP2 (32bit), 2003 (x86), 2008 (x86 and x64), vista (x86 and x64). C:\Users\pierre\Documents\test\php529-1>php 47304.php PHP version: 5.2.9-1 float(-39) float(39) float(17) float(-17) float(-39) float(39) float(17) float(-17) Previous Comments: ------------------------------------------------------------------------ [2009-03-20 15:58:36] pajoye@php.net What is the last version working correctly? ------------------------------------------------------------------------ [2009-02-13 01:00:01] php-bugs at lists dot php dot net No feedback was provided for this bug for over a week, so it is being suspended automatically.

I changed back to PHP version: 5.2.0. Float conversion works fine again now! I'll try it on some different machines, but I won't have time to do that until next week, so you'll hear more from me then. ------------------------------------------------------------------------ [2009-02-05 14:12:07] jani@php.net Eh? How come it worked once but not after that? Can you reproduce this with totally different machine? (works fine still for me on all machines I have, and I have quite a few..) ------------------------------------------------------------------------ [2009-02-05 11:34:19] lennartvdd at mailordersolutions dot nl For some strange reason the problem is reoccurring again with version 5.2.9-dev! Reproduce code: --------------- echo "PHP version: " . PHP_VERSION . "\n"; $var = (float)"-39.000"; var_dump($var); $var = (float)"39.000"; var_dump($var); $var = (float)"17.000"; var_dump($var); $var = (float)"-17.000"; var_dump($var); $var = "-39.000" + 0; var_dump($var); $var = "39.000" + 0; var_dump($var); $var = "17.000" + 0; var_dump($var); $var = "-17.000" + 0; var_dump($var); Actual result: -------------- PHP version: 5.2.9-dev float(-38.:) float(38.:) float(16.:) float(-16.:) float(-38.:) float(38.:) float(16.:) float(-16.:) ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
