Modulus (%) Problem

[tuf-web_co_uk]

Hi,

i'm trying to find out the remainder of a division (if there is one that is)

however when i try my remainder somehow seems to be rounding up.

<?php
$total = 218;
echo $total % 11; // This returns 9


//however
echo $total / 11; // Returns 19.81

// i want the '8' part so i can use it for a another equation
?>

i tried using floor() .... for some reason, however i got no luck.

i also tried 218 / 11 on a calculator, and got 19.8, so why does

218 % 11

return 9, and not 8?

Because 218%11 in fact does return 9.

Reverse the math.
11*19=209
209+9=218

The .81 in the division is not the remainder, per se... Do the Long Division, and you'll see what I mean. The % operator is working perfectly in your example.

   _[u]11[/u]
19|218
  -[u]19[/u]
    28
   -[u]19[/u]
     9

You're confusing the remainder with the decimal part. "9" is the remainder (how many left over after division), which is what modulus returns. If you want the remainder, "9" is what you want.
