Does the same.
It would appear to be. If there is a function to print just to the
digit
could you point me in the direction? So I would want 0.20 0.14 0.16
0.08 respectively.
http://php.net/substring might do what you want.
You'll have to calculate the decimal point for yourself and work from
there.
I use this function to add tax to a price.
Probably it will help you:
function addtax($price,$tax)
{
bcscale(6);
$calc = bcmul(bcdiv($price,100,6),bcadd(100,$tax,6),6);
$output = bcadd (0,$calc,2);
$roundarray = explode (".",$calc);
if (substr($roundarray[1],2,1) >= 5)
{
$output = $roundarray[0]+(substr($roundarray[1],0,2)/100)+0.01;
}
else $output = $roundarray[0]+(substr($roundarray[1],0,2)/100)+0.0;
return $output;
}
