Description:
------------
---
From manual page: http://www.php.net/function.lcg-value
---

The manual page of lcg_value() does not specify if the value is between 0 and 1 inclusive or exclusive.

While it's very safe to assume that 0 is inclusive, it's definitely not obvious if 1 is or isn't.

Thank you for the report, and for helping us make PHP better.

The tests expect any value between 0.0 and 1.0 inclusive, so I've updated the manual to reflect that too. The actual code is somewhat inscrutable, although if anyone really knows their way around LCGs and wants to pull it apart, I'm happy to update it again later.
