is_finite(): to find out legal finite number or not
Check whether a float is finite
is_finite() returns true when a floating-point value is neither infinite nor NAN.
$value = 25.5;
var_dump(is_finite($value)); // bool(true)
This is the recommended starting pattern. The detailed examples below are retained and modernized for additional variations and explanation.
<?Php
echo is_finite(2); Output 1

?>
