php 8 floor fatal error html5 validation

We just upgraded to PHP 8.1 and noticed we got fatal error on floor in

$is_decimal = drupal_strtolower($step) == 'any' || (floor($step) != $step || floor($min) != $min);

This seems to be because default_min which is used for min is set to an empty string instead of 0. Since PHP 8 is way more strict I suggest this should be 0 since its a number field anyways
