This is a valid bug. Thx @YokiToki 👍

Explanation:

One of the validations rules we use for [step] is <value> % <step> === 0. But there are cases, where (x * y) % x !== 0 (e.g. 0.5 % 0.1 === 0.09999999999999998 !== 0). In such cases, ngModelController considers the input value invalid (and sets the model value to undefined).

Affected versions/controls:

1. v1.5.9 (to-be-released): It will affect input[type="range"][ng-input-range] elements on browsers that don't natively support range inputs.
2. v1.6.0-rc.0 (to-be-released): It will affect input[type="number"] elements on all browsers and input[type="range"] elements on browsers that don't natively support range inputs.
