strange, with your code, mine cuts out at 49 significant digits:
3.141592653589793115997963468544185161590576171875
it must be a system-specific limitation.
we need more information on what you are trying to do, *exactly*. be
as detailed and specific as possible.

Dear Jordan,
I know what you mean. But you may try this one and you will know:
<?php
ini_set('precision',200);
echo pi();
?>
the result is the same as 16!!!
So that's why I ask this question! I am not stupid like that!
Please help, thx!

http://us3.php.net/manual/en/ini.core.php#ini.precision
precision sets the number of significant digits, *NOT* the number of
digits displayed after the decimal point.
If you want to get pi out to 16 decimal places you need a
precision of
*17* because the beginning 3 is a significant digit.
Your code does exactly this, displaying pi with 15 decimal places.
