This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. "Operands of modulus are converted to integers (by stripping the decimal part) before processing. " Previous Comments: ------------------------------------------------------------------------ [2007-06-25 14:35:25] [EMAIL PROTECTED] This is how it works in C, hence this is how it should work in PHP. Reclassified as docu problem. ------------------------------------------------------------------------ [2007-06-25 14:18:36] cosborne83 at hotmail dot com Description: ------------ When applying the % (modulo) operator to floats, the values are implicitly converted to int, which causes problems in many instances. This means that you can't use floats to store integer values larger than the maximum int value if you wish to perform modulo operations. Theis behaviour is also invalid since modulo is well defined on floats as well as ints. Reproduce code: --------------- $m = 5000000000; $n = 3.5; // Integer modulo but with large int stored as float print $m % 10; print "\n"; // Non-integer modulo. print $n % 1.5; Expected result: ---------------- 0 0.5 Actual result: -------------- 4 0 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=41802&edit=1
