>> [2 May 2005 11:18am UTC] andrey@php.net 
>> math_std_dev() will be available in 5.1.0

Attempting to access math_std_dev results in unknown function error. 

Reproduce code:
---------------
I don't know the parameters, so I'm just calling the function name to see if it exists. 

$blah = math_std_dev();



Expected result:
----------------
math_std_dev is not currently documented, but was said to appear in 5.1.0.  

Actual result:
--------------
Fatal error:  Call to undefined function math_std_dev() in blahblah.php

It was never added.

It was added and moved to pecl/stats, which is also compatible with PHP4, so one can have the function with PHP4 and PHP5. Very easy to install, and there is a windows extension dll available through pecl.php.net
