Constrains data to numeric values that are less than or equal to max.

max the largest valid number. trim whether or not to trim the input value. validator an optional extra validation step. blank the error message in case of blank field; if omitted, the field will not be made required. malformed the error message for non-numeric input values. large the error message if a number is too large.
