## Introduction to the TRUNC Function

**❑ Objective**

Excel **TRUNC **function truncates a number to an integer by removing the decimal, or fractional, part of the number.

**❑ Syntax**

`TRUNC(number,[num_digits])`

**❑ Argument Explanation**

Argument | Required/Optional | Explanation |
---|---|---|

number |
Required | A number which will be truncated |

num_digits |
Optional | The number of decimal places to return in the truncated number.If this argument is omitted, there will be no decimal part in the returned number. |

**❑ Output**

The **TRUNC** function returns truncated numeric value.

**❑ Version**

This function is available from Excel 2000. So any version since Excel 2000 has this function.

## 4 Examples of Using TRUNC Function in Excel

Now, we will see different examples where various applications of the **TRUNC** function are shown.

### 1. Remove Decimal Parts of a Number

We can remove decimal parts of a number by using the **TRUNC** function. Suppose we have a dataset where we have some numbers with decimal points. Now, we will apply the **TRUNC** function to remove the decimal parts of the numbers.

➤ Type the following formula in cell **C5**,

`=TRUNC(B5)`

The formula will truncate the number of the cell **B5** in such a way that there will be no decimal parts in the returned number.

➤ After that, press **ENTER**.

As a result you will get the integer part of the number of cell **B5 **in cell **C5**.

➤ Now drag the cell **C5 **to the end of your dataset to apply the same formula for all of the numbers.

If you observe you can see that the **TRUNC **function returns zero for any number between 0 to 1.

We can use other functions such as **Excel INT function**, **Excel ROUND function** or **Excel ROUNDDOWN function** instead of the **TRUNC **function to remove decimal parts of a number. The application of these functions for this example are shown in the image below.

### 2. Shorten a Number to a Specific Digit with TRUNC Function

Excel **TRUNC** function can be used to shorten a number to a specific digit. Let’s say, we have some numbers in our dataset in column **B** and the number of digits we want after the decimal point are given in column **C**. Now, we will use the **TRUNC **function to shorten these numbers to specified digits.

➤ First, type the formula in cell **D5**,

`=TRUNC(B5,C5)`

The formula will shorten the number of cell **B5** to the specified digit of cell **C5** and will return the shortened number in cell **D5**.

➤ Press **ENTER**.

And we will get the shortened number in cell **D5.**

➤ At last, drag the cell **D5 **to the end of your dataset.

As a result, we will get all the numbers shortened to the specific digits we have mentioned in column **C**.

If you observe carefully you can see cell **C8 **and **C9** have negative numbers as the digits. The formula eliminates digits from the integer part of the number and returns 0 at that place when the specified digit is negative.

### 3. TRUNC Function to Remove Time from Date and Time Cells

**TRUNC **function can also be used to remove time from date and time cells. Suppose at this time we have some dates and times in our dataset. We want to remove the time part and extract only the date part from these dates and times.

➤ First type the following formula in cell **C5**,

`=TRUNC(B5)`

The formula will truncate the time portion from the date and time of cell **B5**.

➤ After that, press **ENTER**

As a result, you will see the time portion is showing **0:00 **in cell **C5**.

➤ Drag the cell **C5** to the end of your dataset to apply the same formula for all other dates and times.

We can remove the **0:00 **from these cells. To do that,

➤ Go to **Home > Number** and select **Short Date**.

As a result you will see **0:00 **is removed from the cells. Now, we have only the dates.

### 4. TRUNC Function in VBA

**TRUNC** is not a part of the application.worksheetfunction. As a result, it can’t be utilized in Excel **VBA**. But, we can apply **the FORMAT function** to achieve the same result. Suppose we have the following dataset where we want to convert the number with two decimal points.

To do that first,

➤ Press **ALT+F11 **to open the **VBA **window and press **CTRL+G **to open the **Immediate **box in the **VBA **window.

After that,

➤ Insert the following code in the **Immediate **box line by line and press **ENTER **after every line.

```
Range("C5") = Format(Range("B5"), "##.##")
Range("C6") = Format(Range("B6"), "##.##")
Range("C7") = Format(Range("B7"), "##.##")
Range("C8") = Format(Range("B8"), "##.##")
Range("C9") = Format(Range("B9"), "##.##")
Range("C10") = Format(Range("B10"), "##.##")
```

The code will return the numbers of column **C** with two decimal points in column **D**.

➤ Close the **VBA **window.

Now, you will see the numbers with two decimal points in column **C**.

## 💡 Things to Remember When Using TRUNC Function

📌 The **TRUNC **function will give **#VALUE! **error, if you give input in text format.

📌 The **INT **function and the **ROUNDDOWN **function give the same result as the **TRUNC **function. But the **TRUNC **function is easier to use because it requires fewer arguments.

## Conclusion

I hope now you know how the Excel **TRUNC **function works and how to apply the function in different conditions. If you have any confusion please feel free to leave a comment.
