6 Easy Ways to Truncate Decimal in Excel

There are many ways to change decimal numbers. This article especially deals with how to reduce decimal values in Excel. For that, we will use several Functions such as INT, TRUNC, ROUND, ROUNDUP, ROUNDDOWN, and the in-built Number Format.


1. In-Built Number Format to Truncate Decimal

You can easily truncate decimal values in Excel using the in-built Number Format feature. Let’s see the method.

We have taken a dataset of countries and their total population. The population is in the form of 3 point decimals. Now we will truncate this data using this feature.

Steps:

➤ First, select the data range C5:C10 that you want to truncate.

➤ Then, go to Home > Number and click on the Decrease Decimal icon.

So, all the numbers are reduced to 2 point decimal.

2. Use of INT Function to Truncate Decimals

Now we will truncate decimals using the INT function. This function will only give us an integer value and the decimal portion will be dissolved.

We added a new column on the right side of the Population column. In this new column, we will use the function.

Steps:

➤ Write the following formula in D5 and press ENTER.

=INT(C5)

This equation takes a number and gives an integer output.

So, we get our first truncated number which is 1427.

➤ Now, Hold and Drag the D5 cell downward.

Thus, we get all the truncated numbers.

3. TRUNC Function to Truncate Decimal

As the name suggests, the TRUNC function is especially used to truncate decimal numbers. In this method, we will find out 1st and 2nd decimal values using this function.

For that, we have added two columns;1st Decimal and 2nd Decimal.

Steps:

➤ Write the following formula in D5 and press ENTER.

=TRUNC(C5,1)

In this formula,

C5:- the cell we want to truncate

1:- number of digit after decimal

So the decimal value is reduced to the 1st decimal.

➤ Now, Hold and Drag the D5 cell downward.

And, we have all the decimal values reduced to 1st decimal.

Again, we are going to find out the 2nd decimal of these data.

➤ Write the following formula in E5 and press ENTER.

=TRUNC(C5,2)

C5:- the cell we want to truncate

2:- number of digit after the decimal

So, we have got a second decimal for the first number.

➤ Now, Hold and Drag the E5 cell downward.

Thus, all the decimal values are reduced to 2nd decimal.

4. Use of ROUND Function

The ROUND function gives the nearest higher integer value. Its output is somewhat different from the previously shown methods. Let’s see how this is done.

Steps:

➤ Write the following formula in D5 and press ENTER.

=ROUND(C5,1)

In this equation,

C5 is the cell we want to truncate.

1 is the number of digit we want after the decimal.

Truncate Decimal in Excel

So we have our first truncated decimal.

➤ Now, Hold and Drag the D5 cell downward.

Thereby, all the decimal values are reduced to 1st decimal.

Now, let’s say we don’t want any digit after the decimal.

➤ So write the following formula in E5 and press ENTER.

=ROUND(C5,0)

C5 is the cell we want to truncate.

0 is the number of digit we want after the decimal.

Truncate Decimal in Excel

So we get our first integer value.

➤ Now, Hold and Drag the E5 cell downward.

Thereby we have all the decimal values reduced as integers.

5. Using ROUNDUP Function to Truncate Decimal

The ROUNDUP function rounds the numbers to the next higher possible value. This method will take the value from column C and round them in two different criteria. Let’s see how it can be done.

Steps:

➤ First, write the following formula in D5 and press ENTER.

=ROUNDUP(C5,1)

C5 is the cell we want to truncate.

1 is the number of digit we want after the decimal.

So, we get our first modified value. You can see that the outcome value is higher than the original one.

➤ Now, Hold and Drag the D5 cell downward.

Truncate Decimal in Excel

Thus, we have all the decimals modified using the function

Now, we will reduce these decimals into integers.

➤ Write the following equation in E5 and press ENTER.

=ROUNDUP(C5,0)

C5 is the cell we want to truncate

0 is the number of digit we want after the decimal.

Truncate Decimal in Excel

So, we have our first value rounded up.

➤ Now, Hold and Drag the E5 downwards.

Thereby we get all the rounded up values.

6. Use of ROUNDDOWN Function

The ROUNDDOWN function is just the opposite of the previous method. This function gives us the nearest lower value for a given number.

Steps:

➤ Write the following equation in D5 and press ENTER.

=ROUNDDOWN(C5,1)

C5 is the cell we want to truncate

1 is the number of digit we want after the decimal.

Thus, we have got our first rounded down number.

➤ Now, Hold and Drag the D5 cell downward.

Truncate Decimal in Excel

Thereby, we have all the decimal values rounded down to 1st decimal.

Again, we want to get integer values using this very function.

➤ Write the following equation in E5 and press ENTER.

=ROUNDDOWN(C5,0)

C5 is the cell we want to truncate

0 is the number of digit we want after the decimal.

Truncate Decimal in Excel

So, we get our first rounded down value.

➤ Now, Hold and Drag the E5 cell downward.

Thus, all the decimal values are rounded down as integers.
