The final version of function to check the actual float value and return boolean(true/false).

public function isTrueFloat($val)  { if(is_string($val)) $val = trim($val); if( is_numeric($val) && ( is_float($val) || ( (float) $val > (int) $val || strlen($val) != strlen( (int) $val) ) && (ceil($val)) != 0 )) { return true; } else return false; } The following are the test results from the above function. //Tests '4.0' returns true '2.1' returns true 0 returns false "0" returns false 3. returns true 13 returns false "12" returns false 3.53 returns true // Additional Tested ones "0.27" returns true 0.24 returns true
