Hello!

echo $var2 // Return 1133244
$var2 return the correct result, but $var1 is wrong (the correct
result is 9067640)
Probably because the maximum signed 32 bit integer value is
2,147,483,648
OK, but with bigger numbers works fine again.
Right now I made a function to deal with this issue:
function remainder($dividend,$divisor){
$remainder= $dividend-(floor($dividend/$divisor)*$divisor);
return $remainder;
}
What do you think about it?
That will convert the numbers to floating point, which will give you
round off error if the numbers get too big.
