<?php echo 1 / -2 * 5; // -0.1 $a = 2; echo 1 / -$a * 5; // -0.1 $a = -2; echo 1 / $a * 5; // -2.5 echo 1 / -$a * 5; // 0.1 ?> Looks like a problem with the parsing of unary negation. Previous Comments: ------------------------------------------------------------------------ [2007-05-16 18:24:03] [EMAIL PROTECTED] This IS a bug. http://de.php.net/operators lists unary - having higher precedence than the arithmetic operators, and that is the way it should be. So, this statement should evaluate to 1/(-2)*5 and that is -2.5 and not -0.1. ------------------------------------------------------------------------ [2007-05-16 12:50:59] [EMAIL PROTECTED] Sorry, but your problem does not imply a bug in PHP itself. For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. ------------------------------------------------------------------------ [2007-05-15 15:44:07] drlippman at yahoo dot com Description: ------------ Left-to-right order of operations does not appear to be honored when dividing by a negative Reproduce code: --------------- 1/-2*5 Expected result: ---------------- -2.5 Actual result: -------------- -.1 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41401&edit=1
