(PHP 3, PHP 4, PHP 5)

bcscale --  Set default scale parameter for all bc math functions

Description

bool bcscale ( int scale )

This function sets the default scale parameter for all subsequent bc math functions that do not explicitly specify a scale parameter. 如果成功则返回 TRUE,失败则返回 FALSE

例子 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
