IV. BCMath Arbitrary Precision Mathematics Functions
For arbitrary precision mathematics PHP offers the Binary Calculator which
supports numbers of any size and precision, represented as strings.
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.
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.
This extension does not define any
configuration directives.
This extension does not define any resource types.
This extension does not define any constants.
