I have this

Math.round((Math.abs(21600 / 3600))*100)/100
>> 6 # want 6.00
Math.round((Math.abs(21000 / 3600))*100)/100
>> 5.83 # This is right

I need 2 decimals on whole number.

You can use .toFixed(), but there's no need to manually round the value to the nearest 0.01 first - the .toFixed function will do that for you.

var str = Math.abs(21600 / 3600).toFixed(2);

Use Number.prototype.toFixed()^MDN.

(Math.round((Math.abs(21600 / 3600))*100)/100).toFixed( 2 );

Try this:

(Math.round((Math.abs(21600 / 3600))*100)/100).toFixed(2)

You can use toFixed() method:

var num = num.toFixed(6);

Now num wil be equal to 6.00
