Ok. Thanks for your answer and the reference. Previous Comments: ------------------------------------------------------------------------ [2007-06-19 05:09:45] [EMAIL PROTECTED] 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. ------------------------------------------------------------------------ [2007-06-18 23:48:42] mc at glouglou dot net Description: ------------ Came up with this numbers in a web-app. I've tested this on various platform (Linux/Windows) and PHP version 4.3.9, 5.1, 5.2.1 and 5.2.3 with default php.ini Reproduce code: --------------- <?php echo(859-832.35-26.65) ?> Expected result: ---------------- 0 Actual result: -------------- -2.13162820728E-14 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41733&edit=1
