What is PhpDig?
PhpDig is a PHP MySQL based
Web Spider & Search Engine.



bcscale — Sets scale.


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


Always TRUE


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.


Existing since version 3.0


Example 13. Set scale to two decimal places

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