The Multiples(Ints) validator checks if a give value is a multiple of some other value (the divisor).

This validator only works for Ints and there is no reason for this.

A perfectly valid example would be requiring for values to be multiples of 20ns.

The current value would then be valid 40e-9 as this would return 0.0. Currently this will raise an error as 40e-9 (which is a multiple of 20e-9) raises an error as it is not an Int. I propose dropping the constraint of it having to be an Int.
