Previous Comments: ------------------------------------------------------------------------ [2010-11-06 00:47:07] frozenfire@php.net Automatic comment from SVN on behalf of frozenfire Revision: http://svn.php.net/viewvc/?view=revision&revision=305119 Log: Added an example to the Math extension's mt_getrandmax function, as per bug #53207. ------------------------------------------------------------------------ [2010-11-05 20:43:51] frozenfire at thefrozenfire dot com I have added a patch which adds the proposed example to the mt_getrandmax function. Previously, there was no examples refsect, so that was added as well. I included two instance of the output; both with and without parameters to the function. ------------------------------------------------------------------------ [2010-10-30 17:49:53] + at ni-po dot com Ooops, I'm sorry, the code should be: // calculate random floating point number function randomFloat($min = 0, $max = 1) { return $min + mt_rand() / mt_getrandmax() * ($max - $min); } echo randomFloat(0, 1); Fixed wrong range calculation and use $min / $max instead of $from / $to. ------------------------------------------------------------------------ [2010-10-30 17:41:18] + at ni-po dot com Description: ------------ I want to propose an example for mt_getrandmax: Code: // calculate random floating point number function randomFloat($from = 0, $to = 1) { return $from + mt_rand() / mt_getrandmax() * $to; } echo randomFloat(0, 1); Sample Output: 0.32345942003814 As generating uniform random values in the mathematical sense is the only application I see for mt_getrandmax I think this should be included. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=53207&edit=1
