How can I turn input type="tel" into a variable with a number?

Question

I want a user to input a number into input type="tel" or type="number" and then to make a variable with this number for further calculations. So far it is unable to identify a number. Any ideas?

function digit() {
    var num = document.getElementById('inpt');
    document.body.innerHTML = num;
}

<input onchange="digit()" type="tel" name="numb" id="inpt" />

Set an event listener to changes of this input, then update the value of variable as it is mentioned above — Sergey, Sep 12 '17 at 14:21
Telephone numbers, despite the name, aren't *numbers*. They're strings. Don't tell me my mobile is `7712345678`. It's `07712 345 678`. My work number may well be `020 1234 5678 ext. 10`. Or `1 (408) 555-1234`. — T.J. Crowder, Sep 12 '17 at 14:21

try this

<script>
function digit() {
    var num = document.getElementById('inpt').value;
    document.body.innerHTML = num;
}
</script>

if it's not correct try this

console.log(document.getElementById('inpt'))

and show the object in browser console
