NG Absolute Form Validator - V14.1

Integer

The Integer rule checks that a value is a whole number, with no decimal component — the right choice for fields like a quantity, an age, or an item count where a fractional value wouldn't make sense. A string representation of a whole number, like '42', passes just as a native number 42 would, so values coming straight from an HTML input still validate correctly. A decimal value such as 42.5 fails; if you need to allow decimals as well, the Number rule is the broader check to use instead.
