 * version 1.02
 * fix the problem when precision has been set and the input start with decimal dot or comma ,e.g. precision set to 3 and input with ".1234"
 *
 * @ VERSIONE 1.1 MODIFICATA DA FILIPPO BRAZZO
 * Se un numero ha decimali allora accetto anche i caratteri ., poi la formatN sistsema il valore
