You'll need to complain to whatever distribution you are using.
We don't define the value unless math.h doesn't define it for some wacky reason
on your platform, in which case we fallback on 3.14159265358979323846.

Description:
------------
php doesn't calculate the correct value of pi
Test script:
---------------
php-cli -r 'ini_set('precision','100'); echo pi();'
or
<?
ini_set('precision','100');
echo pi()."\n"; exit;
?>
Expected result:
----------------
3.141592653589793238462643383279502884197169399375
Actual result:
--------------
3.141592653589793115997963468544185161590576171875
