Set default scale parameter for all bc math functions

Description

int bcscale ([ int $scale ] )

Sets the default scale parameter for all subsequent calls to bc math functions that do not explicitly specify a scale parameter. If scale is omitted, the function gets the current scale factor.

Parameters

scale: The scale factor.

Return Values

Returns the old scale.

Changelog

Version	Description
7.3.0	bcscale() can now be used to get the current scale factor; when used as setter, it now returns the old scale value. Formerly, `scale` was mandatory, and bcscale() always returned `TRUE`.

Examples

Example #1 bcscale() example


<?php

// default scale : 3
bcscale(3);
echo bcdiv('105', '6.55957'); // 16.007

// this is the same without bcscale()
echo bcdiv('105', '6.55957', 3); // 16.007

?>
