We have introduced the ROUNDUP() Function of Excel in Microsoft Access earlier. It works like the ROUND() Function except that the number is always rounded up. When a number of digits are greater than 0 (zero), then the number is rounded up to the specified number of decimal places. If a number of digits specified are 0 (zero), then the number is rounded up to the nearest integer.

The ROUNDUP() Function of Excel in Access.
The ROUNDDOWN() Function of Excel does the opposite of the ROUNDUP() Function. When the number of digits specified is greater than 0 (zero) then the number is rounded down to the specified number of Decimal Places. If the number of digits specified is 0 (zero) then the number is rounded down to the nearest integer.
Syntax:
ROUNDDOWN(Number, num_digits)
Number: Required, Any Real Number.
num_digits: Required, Number of Digits the Number to Round Down to.
