BankRound
Use this function to round numbers based on Banker’s rounding. With Banker’s rounding, values below 0.5 go down and values above 0.5 go up. Values of exactly 0.5 go to the nearest even number. In contrast, the Round function always rounds 0.5 upwards.
| Note | When you add values which have been rounded using the standard method of always rounding .5 in the same direction, the result includes a bias that grows as you include more rounded numbers. Banker’s rounding is designed to minimize this. |
