[Resolved] [Resolved] Need help with rounding

[n00854180t]

I need to see if a variable is over 100 and if it is, take whatever amount it is over 100 and multiply that by a number, then round the number up. Now I know how to round the number and everything but how do I take only the last 2 digits?

Try this:

if($var>100){
$var2 = $var-100;
$var3 = round($var2 * $num);

}

This should be it... But if you want to get last two digits of the $var3 (if that's what you want) you should put in this line, too:

$res = substr($var3,-2);

That should do it... If I didn't understand you correctly or this isn't working - let me now...

Thanks but I need help with one more thing. If the $totalCost variable is over 200 I need to take the last two digits and multiply it by a different number. Basically I need to make it so that the discount is 7.5% of the price over 100 and 10% of the price over 200. So if they had 199 they would get 99 7.5%. If they had 201 they would get 1 10%.

I have this code so far for this.

if  ($totalCost > 100)
{
$discountUR = $totalCost - 100 * 0.075;
$discountVar = (ceil($discountUR/1))* 1;
} elseif ($totalCost > 200)
{
$discountUR = 99 * 0.075;
$discountUR2 = $totalCost - 200 * 0.100;
$discountRnd = (ceil($discountUR2/1))* 1;
$discountVar = $discountRnd + $discountUR2;
}

Okay I figured it out, thanks!
