[QUOTE="Josselin, post: 4536943"] After reading completely my Ruby book, I cannot find a function equivalent to the PHP is_numeric? to test a String myString.is_numeric? (check only digits and dot character) => return true or false does it exist ? or it's more complicated than that ? (need to build a regex... ?) thanks joss [/QUOTE]
