 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;
  }

[PHP] printf and number_format rounding

Are printf and number_format supposed to round?

echo ($hcount-$lcount)/$hilow. ;
echo number_format(($hcount-$lcount)/$hilow,2,'.','');

0.145833 0.15 
0.17 0.17 
0.083 0.08
