bcscale

Name

bcscale — Sets scale.

Synopsis

string bcscale(scale); int scale: Number of decimal places

Description

bcscale() can be used with all BC math functions. It sets the default number of decimal places to return for all BC math functions if the scale is not passed as a parameter to the function. Naturally, if the number is defined in the function, the value in bcscale() is overridden.

Version

Existing since version 3.0

Example

Example 13. Set scale to two decimal places

$num1 = "9912343.34546";
$num2 = "1";
echo bcmul($num1, $num2) . "\n";
// 2 decimal places
bcscale(2);
echo bcmul($num1, $num2);

Output:
9912343
9912343.34
