How to Use Excel ROUNDUP Function? (Formula with Examples)

What Does ROUNDUP Function Do in Excel?

ROUNDUP function in excel is an inbuilt function in excel which is used to calculate the rounded value of the number to its highest degree, or in other words it rounds the number away from zero so if the input provided to this function is =ROUNDUP(0.40,1) we will get 0.4 as a result, this function takes two arguments one being the number and another is the number of digits.

Syntax

Parameters

As it is clear from the syntax shown above the ROUNDUP formula has two parameters which are as follows:

Number: The number parameter is a mandatory parameter of the ROUNDUP formula. It defines the floating point number which needs to be rounded up.
Num_of_digits: This parameter is also mandatory for the ROUNDUP ROUNDUP formula to work. This parameter defines the number of digits you would like to round the provided Number to. This parameter can be positive, negative or zero.
If Num_of_digits = 0: It means the Number will be rounded up to the nearest integer number.
If Num_of_digits < 0: It means the Number will be rounded up to the nearest 10, 100, 1000, and so on; depending upon the value of Num_of_digits.
If Num_of_digits > 0: It means the Number will be rounded up to the number of decimal places defined by the value of Num_of_digits

These conditions will be much clearer with the help of examples explained in the next section.
