# How to Convert Decimal to Whole Number in Excel: A Step-by-Step Guide

How to Convert Decimal to Whole Number in Excel

Converting decimal numbers to whole numbers in Excel is a breeze once you know the steps. You can use functions like `INT`, `ROUND`, or `TRUNC` to achieve this. Each method has its unique purpose, but they all help you get rid of decimal points. Ready to learn how? Let’s dive in!

## Step-by-Step Tutorial for Converting Decimal to Whole Number in Excel

In this section, we’ll cover how to convert decimal numbers to whole numbers using different Excel functions. Each step will guide you through the process, so you can choose the method that best fits your needs.

### Step 1: Open Excel and Select Your Data

In this step, you need to open your Excel spreadsheet and select the cell or column containing the decimal numbers you want to convert.

Make sure your data is highlighted so you can easily apply the necessary functions. If you have a large dataset, selecting the entire column might be more efficient.

### Step 2: Use the INT Function

First, type `=INT(cell)` into a new cell where you want the whole number to appear. Replace "cell" with the reference of the cell containing the decimal.

The `INT` function will always round down to the nearest whole number. For example, if your number is 3.9, it will convert to 3.

### Step 3: Use the ROUND Function

Alternatively, you can use the `ROUND` function. Type `=ROUND(cell,0)` into a new cell. Again, replace "cell" with the reference of the cell containing the decimal.

The `ROUND` function allows you to round numbers to the nearest whole number. It’s beneficial when you need standard rounding rules applied.

### Step 4: Use the TRUNC Function

To truncate a number, type `=TRUNC(cell)` into a new cell. Replace "cell" with the reference of the cell containing the decimal.

The `TRUNC` function removes the fractional part of the number, similar to `INT`, but without rounding.

### Step 5: Copy the Formula Down

Drag the fill handle (a small square at the bottom-right corner of the cell) down to apply the formula to other cells in the column.

This allows you to quickly convert an entire column of decimal numbers to whole numbers, saving you time and effort.

After completing these steps, your selected decimal numbers will be converted to whole numbers according to the function you used.

## Tips for Converting Decimal to Whole Number in Excel

• Choose the Right Function: Select `INT` for always rounding down, `ROUND` for standard rounding, and `TRUNC` for truncating without rounding.
• Use Fill Handle: To quickly apply the function to multiple cells, use Excel’s fill handle feature.
• Combine Functions: Sometimes, combining functions like `ROUND` and `TRUNC` can give you more control over the conversion process.
• Use Cell References: When applying formulas, use cell references instead of typing in numbers directly for flexibility.

### What is the difference between INT and TRUNC?

The `INT` function rounds down to the nearest whole number, while the `TRUNC` function simply removes the decimal part without rounding.

### How can I apply the conversion to multiple cells at once?

Use the fill handle to drag the formula down the column, applying it to multiple cells simultaneously.

### Can I round numbers to the nearest whole number?

Yes, use the `ROUND` function by typing `=ROUND(cell,0)` to round numbers to the nearest whole number.

### What if I want to round up instead of rounding down?

Use the `CEILING` function (e.g., `=CEILING(cell,1)`) to always round up to the nearest whole number.

### How do I know which function to use?

Choose `INT` for rounding down, `ROUND` for standard rounding, and `TRUNC` to simply remove the decimal part.

## Summary of Steps

1. Open Excel and select your data.
2. Use the INT function.
3. Use the ROUND function.
4. Use the TRUNC function.
5. Copy the formula down.

## Conclusion

There you have it! Converting decimal to whole numbers in Excel isn’t rocket science, but knowing the different functions—whether it’s `INT`, `ROUND`, or `TRUNC`—can make your life a lot easier. Each function serves a unique purpose, so choose the one that fits your needs best.

Remember, Excel is a powerful tool, and mastering these functions can significantly speed up your data processing tasks. Whether you’re dealing with sales data, scientific measurements, or just a long list of numbers, converting decimals to whole numbers will help you present your data more cleanly and effectively.

So, next time you find yourself stuck with decimal numbers that need converting, just follow these steps, and you’ll be on your way in no time. Happy Excel-ing!
