Question

In my database, I store money values without any points or commas.
So I need a Javascript function that converts it into money string.

Example: Convert 500 (five dollars) into 5.00 , 100 into 1.00, 550 into 5.50 etc

Can anybody post a function like that?

Answer 1

You can use something like:

function toAmount(amount){
  amount = Number(amount);
  if (isNaN(amount)){
    throw 'invalid: can\'t convert input';
  }
  return (amount/100).toFixed(2);
}
//usage
toAmount(500);    //=> 5.00
toAmount(520873); //=> 5208.73
toAmount('500');  //=> 5.00

Or use that function as an extension to Number

Number.prototype.toAmount = function toAmount(amount){
  return (this/100).toFixed(2);
};
//usage:
(500).toAmount();    //= 5.00
(520873).toAmount(); //=> 5208.73
