checking if a number is float in PHP

Question

This is really weird. I have this piece of code.

$rewardAmt = $amt;
if(is_float($rewardAmt)){
      print_r(\"is float\");die;
} else {
      print_r(\"is no

You can check this by

$float = floatval($num); //Convert the string to a float
if($float && intval($float) != $float) // Check if the converted int is same as the float value...
{
    // $num is a float
}else{
    // $num is an integer
}
