convert float to hours using momentjs

Question

For example, how to convert this float number 6.5 to "06:30" using momentjs?

I've tried this:

moment("6.5", "hh:mm").format("HH:mm"))

but it outputs:

06:05

If you just need to convert your float to string you can create a duration object and then display it as string using moment-duration-format plug-in.

Here a working example:

var dur = moment.duration(6.5, 'h');
console.log(dur.format('HH:mm'));
