title: Validating input with vue.js - what does v-model.number really mean?
body: <p>If I have specified that my input field is numeric, with <code>v-model.number</code>, what assumptions can I make for validating the numeric input prior to form submission (or rather, posting JSON to the server)? I.e., can I assume that it is always going to be a number at this point, and can therefore concentrate on testing whether it falls within a certain range, say? Or do I still need to test isNan, etc?</p>
