IV. BCMath Arbitrary Precision Mathematics Functions
In PHP 4, these functions are only available if PHP was configured with
--enable-bcmath.
In PHP 3, these functions are only available if PHP was not configured with
--disable-bcmath.
Note:
Due to changes in the licensing, the BCMATH library is distributed
separate from the standard PHP source distribution.
You can download the tar-gzipped archive at the url:
http://www.php.net/extra/number4.tar.gz. Read the
file README.BCMATH in the PHP distribution
for more information.
