Format number to always show 2 decimal places

Question

I would like to format my numbers to always display 2 decimal places, rounding where applicable.

Examples:

number     display
------     -------
1            


        

Answer 1

Try below code:

function numberWithCommas(number) { 

   var newval = parseFloat(Math.round(number * 100) / 100).toFixed(2);

   return newval.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}
