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. Thus, this file should be as light as possible.

round( $op1, $precision = 0) : void

static

Surprisingly, the results of this implementation of round() prove better than the native PHP round().

For example, try: round(639.795, 2); round(267.835, 2); round(0.302515, 5); round(0.36665, 4); then try: Zend_Locale_Math::round('639.795', 2);

Parameters
