Package: Zend\Locale

Utility class for proxying math function to bcmath functions, if present, otherwise to PHP builtin math operators, with limited detection of overflow conditions.

Sampling of PHP environments and platforms suggests that at least 80% to 90% support bcmath. This file should only be loaded for the 10% to 20% lacking access to the bcmath extension.
