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?
if you are dealing with numbers that large, consider using some arbitrary
precision math functions that can work with as large of numbers as you need.
