Hi,
To Set default scale parameter for all bc math functions we can use bcscale() function. This function sets the default scale parameter for all subsequent bc math functions that do not explicitly specify a scale parameter.
For e.g
PHP Code:
<?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
?>
