Excel formulas: ROUND, ROUNDUP, and ROUNDDOWN - Beginner Step-by-Step Tutorial

 The ROUND, ROUNDUP and ROUNDDOWN functions in Excel finds its utility in various practical scenarios across different fields. In finance, it is used to round monetary values, interest rates, or exchange rates to a specified number of decimal places, ensuring clear and concise representation. Engineers and scientists employ it to manage measurement units with precision, rounding lengths, weights, or time values. When working with percentages, ratios, or statistical analyses, rounding becomes crucial to maintain data readability without compromising overall accuracy. Additionally, in educational settings, grades can be rounded to offer fair and straightforward assessments. Whether presenting data in charts, reports, or currency conversion tasks, the ROUND, ROUNDUP and ROUNDDOWN functions prove to be an indispensable tool for optimizing data representation and simplifying complex calculations.

Now lets get to it:

The ROUND Formula: Rounding Numbers

The ROUND formula is handy when you want to round a number to a specific number of decimal places. Imagine you have a sales sheet with numbers like 45.6789, 98.1243, and 23.5674, and you'd like to round them to two decimal places for clarity.

The formula syntax is: =ROUND(number, num_digits)

number: The cell reference or value you want to round.
num_digits: The number of decimal places you want the rounded result to have.

Example: If A1 has a value of 45.6789, and you want to round it to remove all decimals then, the formula would be =ROUND(A1,0), equal to 46.

The ROUNDUP Formula: Always Round Up

ROUNDUP is similar to ROUND, but it always rounds a number up to the nearest specified decimal place. This can be helpful when you need to ensure that there's no rounding down involved.

The formula syntax is: =ROUNDUP(number, num_digits)

number: The cell reference or value you want to round.
num_digits: The number of decimal places you want the rounded result to have.

Example: If A1 has a value of 45.6789, and you want to round it to only have two decimals then, the formula would be =ROUNDUP(A1,2), equal to 45.68.

The ROUNDDOWN Formula: Always Round Down

On the other hand, ROUNDDOWN always rounds a number down to the nearest specified decimal place.

The formula syntax is: =ROUNDDOWN(number, num_digits)

number: The cell reference or value you want to round.
num_digits: The number of decimal places you want the rounded result to have.

Example: If A1 has a value of 45.6789, and you want to round it to only have two decimals then, the formula would be =ROUNDDOWN(A1,2), equal to 45.67.

Let's Try It Out!

Imagine you have the following numbers in cells A1, A2, and A3: 45.6789, 98.1243, and 23.5674. To round these numbers to two decimal places, use the formulas as follows:
In cell B1:=ROUND(A1, 2)
In cell B2:=ROUNDUP(A2, 2)
In cell B3:=ROUNDDOWN(A3, 2)
