As mentioned in #275, I'd rather not merge this. Make sure your data is good before it arrives at angular-gettext.

JS might not be strongly-typed, but that doesn't mean that types don't matter. Strings aren't numbers, the only person who knows if a conversion can be done safely is you.

so you're telling me, every single time i use angular-gettext with input(type=range), i need something like this?
