I object to this as an alias for is_float(), because 2.1 is no more "real" as a number than 2.0 (which is automatically cast to int, and therefore is_real(2.0) === false).

@jesdisciple: Not so. <?php is_real(2.0) //evaluates to TRUE ?> For proof, see this: http://demo.pixelsandpages.com/is_float_int_real.php
