1.2.65. Avoid Real¶
PHP has two float data type : real and double.
realis 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;
}
?>
