Bug #12550 Updated: rand() and mt_rand() don't behave as documented

ID: 12550 Updated by: sniper Reported By: sulka@sulake.com Old Status: Open Status: Analyzed Old Bug Type: Math related Bug Type: Documentation problem Operating System: N/A PHP Version: 4.0.6 New Comment: The documentation is wrong. The proto is this: mt_rand([int min, int max]) --Jani Previous Comments: ------------------------------------------------------------------------ [2001-08-03 08:13:29] sulka@sulake.com In PHP documentation rand() and mt_rand() parameters are specified as "([int min [, int max]])" which implies max is optional when min is specified, so that rand(256) would return a number ranging from 256 to getrandmax(). This is not supported however. Looking at rand.c, it looks like the author partially implemented this and forgot to add the relevant code to the portion that parses the parameters on both functions. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=12550&edit=1
