actually, nr should be a positive non-zero integer, so how about if (!nr || nr < 1 || (nr | 0) !== nr)?
Number.isInteger doesn't exist in IE, but maybe that's not an issue?

Good point, that seems good to me!
Oh no, I didn't thought about that. The polyfill is actually quite simple:
Number.isInteger = Number.isInteger || function(value) {
return typeof value === 'number' &&
isFinite(value) &&
Math.floor(value) === value;
};Of course we shouldn't actually polyfill it but maybe just do these checks in the if clause.
Number.isFinite() seems to have an implemented in all browsers.

I mistakenly assumed that 0.5 rps would work…
