This article describes the formula syntax and usage of the ROUNDUP function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Rounds a number up, away from 0 (zero).
The ROUNDUP function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Number Required. Any real number that you want rounded up.
- Num_digits Required. The number of digits to which you want to round number.
- ROUNDUP behaves like ROUND, except that it always rounds a number up.
- If num_digits is greater than 0 (zero), then number is rounded up to the specified number of decimal places.
- If num_digits is 0, then number is rounded up to the nearest integer.
- If num_digits is less than 0, then number is rounded up to the left of the decimal point.
The example may be easier to understand if you copy it to a blank worksheet.
