Post language: The round function says rounding seems to be different from what we usually say, our usual is: is greater than or equal to 5 of the value, less than 5 of the value of the shed. But the round function is more than 5 of the value, less than 5 of the value of the house, equal to 5 of the odd number into even homes, so always feel a bit inconsistent with the habit, so still use the FormatNumber function bar.
