Is there a simple way to convert a decimal time (e.g. 1.074 minutes) into mm:ss format using moment.js?

I was wondering if there's a simple way, using moment.js library, to transform a decimal time interval (for example, 1.074 minutes) into its equivalent 'mm:ss' value. I am currently using a function which doesn't work too well with negative times (it outputs the value in '-m:ss' format):

function secTommss(sec){

 var min = Math.floor(sec/60)

 sec = Math.round(Math.abs(sec) % 60);

 return min + : + (sec < 10 ? 0 + sec : sec)

}

Here is some JavaScript that will do what you are asking:

function minTommss(minutes){

 var sign = minutes < 0 ? - : ;

 var min = Math.floor(Math.abs(minutes));

 var sec = Math.floor((Math.abs(minutes) * 60) % 60);

 return sign + (min < 10 ? 0 : ) + min + : + (sec < 10 ? 0 : ) + sec;

}

Examples:

minTommss(3.5)        // 03:30

minTommss(-3.5)       // -03:30

minTommss(36.125)     // 36:07

minTommss(-9999.999)  // -9999:59

You could use moment.js durations, such as

moment.duration(1.234, 'minutes')

But currently, there's no clean way to format a duration in mm:ss like you asked, so you'd be re-doing most of that work anyway.
