      return (this.carts || []).reduce(function (items, data) {
        return items   parseFloat(data.games.price * data.quantity)
      }, 0)
    }

but the result i dont get decimal number like 400.000

i change the parseFloat to parseInt but nothing happen

CodePudding user response：

Do not parse your number, and then try to add that string to your accumulator, in your reducer.

If you want to print a numeric string with 3 decimal places:

totalPrice() {
      return (this.carts || []).reduce(function (items, data) {
        return items   (data.games.price * data.quantity)
      }, 0.0)
    }

const str = totalPrice().toFixed(3)

totalPriceString() {
  return totalPrice().toFixed(3)
}
