Convert minutes into hours and minutes 2

[DoctorGonzo]

Hi guys,

Need help with a javascript / maths problem.

I have a field which contains a number of minutes.

I need to convert this into hours and minutes though.

If I simply divide the field by 60, this gives me a DECIMAL ie. 350 (mins) divided by 60 returns 5.83 hours... but what needs to be returned is 5 hours 50 minutes.

Can anyone help with this? I'm thinking I will pass the minutes value to some sort of function.....

var s="350"; //get from the field say
var t;
if (/^\d*\.{0,1}\d*$/.test(s)) { //decimal separator "."---know your users
t=Math.floor(parseInt(s,10)/60)+" hours "+((parseFloat(s,10)%60).toFixed(0))+" minute(s)";
} else {
t="Not a number." //or whatever you want to show or do
}
[/tt]

Another way, without validation

function toHoursAndMinutes(minutes) {
var mins = minutes%60; //modulus dividing by 60
var hrs = (minutes - mins)/60; //Now you get an integer division
alert(hrs+":"+mins);
}

Cheers,
Dian

Upon re-reading my post, I want to close a catch related to rounding.
