1.2.66. Avoid Real

PHP has two float data type : real and double. real is rarely used, and might be deprecated in PHP 7.4.

To prepare code, avoid using is_real() and the (real) typecast.

<?php

// safe way to check for float
if (!is_float($a)) {
    $a = (float) $a;
}

// Avoid doing that
if (!is_real($a)) {
    $a = (real) $a;
}

?>
