Round and Round: Excel’s INT Function Unveiled

Title: Mastering Excel’s INT Function: Your Guide to Rounding NumbersHave you ever wondered how to effortlessly round numbers in Excel? Look no further than the INT function! In this article, we will explore the ins and outs of Excel’s INT function, equipping you with the knowledge to round numbers with ease.

Whether you want to simply remove the decimal portion or round down to the nearest whole number, the INT function is here to save the day. So, let’s dive in and unravel the mysteries of this powerful Excel tool!

The Basics of the INT Function

Removing the Decimal Portion

When working with numerical data in Excel, you may encounter situations where you only need the whole number, discarding any fractions. The INT function, short for “integer,” allows you to achieve this effortlessly.

By applying the INT function to a cell, you can eliminate the decimal portion and obtain the underlying data.

Understanding the Syntax and Arguments

Excel versions may vary, but the syntax of the INT function remains consistent. To utilize its power, you must familiarize yourself with the function’s syntax and argument requirements.

By mastering these nuances, you can unleash the full potential of the INT function on any Excel version at your disposal.

How to Enter the INT Function

Manual Entry or Using the Dialog Box

Entering the INT function can be done in different ways depending on your preference. Some Excel users prefer manual entry, typing out the INT function followed by the desired cell or value.

Alternatively, you can also use the handy dialog box, which guides you through the process step by step, ensuring accuracy. INT Function vs.

TRUNC: The Rounding Dilemma

While the INT function is perfect for rounding down to the nearest whole number, what if you encounter negative numbers or need to truncate decimal portions without rounding? Enter the TRUNC function.

Understanding the differences between the INT and TRUNC functions allows you to choose the appropriate rounding method for your specific needs.


In conclusion, the INT function is an invaluable tool in Excel that simplifies the process of rounding numbers. By learning how to use it effectively, you can eliminate decimal portions and round down to the nearest whole number with ease.

Remember to familiarize yourself with the syntax and arguments of the function, and explore the use of the dialog box for a hassle-free entry experience. Additionally, be aware of scenarios where the TRUNC function may be more suitable for your rounding needs.

With these skills in your arsenal, you’ll be well-equipped to tackle any rounding challenge in Excel.

Rounding in Reverse – Obtaining Decimal Values

Returning Decimal Values Using the INT Function

So far, we have focused on rounding down and removing the decimal portion of numbers using the INT function. However, there may be instances where you want to obtain the decimal portion alone.

Excel offers a simple formula using the INT function to achieve this. To return the decimal values, subtract the integer portion from the original number.

Let’s say we have the value 7.89 in cell A1. In cell B1, enter the formula “=A1-INT(A1)”, and voila! You will get the decimal portion, 0.89, displayed in cell B1.

This formula subtracts the rounded-down integer portion of A1, leaving behind just the decimal values.

An Alternative Formula – The MOD Function

While the formula discussed above works perfectly for obtaining decimal values, there is an alternative method using the MOD function. The MOD function calculates the remainder when one number is divided by another.

By selecting an appropriate divisor, we can remove the integer portion and keep only the decimal values. To achieve this, use the formula “=MOD(A1,1)” in cell B1.

The number 1 acts as the divisor, causing the MOD function to calculate the remainder when A1 is divided by 1. The result is the decimal portion of A1, just as we desired.

Now, you may wonder why the divisor is set as 1. When dividing any number by 1, the result is the same number itself, while the remainder is always 0.

By using a divisor of 1, we effectively remove the integer portion from the original value, leaving us with only the decimal values. The MOD function can be a powerful tool when manipulation of decimal values is required.

By choosing an appropriate divisor, you can control the precision and obtain desired results for further analysis or calculations.


With a solid understanding of Excel’s INT function and its ability to round numbers, both “up” and “down,” we have uncovered a range of powerful techniques to manipulate decimal values. By using the INT function with subtraction or combining it with the MOD function, you can easily obtain the underlying decimal data or isolate the decimal portion for further analysis.

Remember that knowing the syntax and arguments of the INT function is essential, as it ensures consistent functionality across various Excel versions. Additionally, consider the TRUNC function as an alternative when rounding requirements involve situations such as negative numbers or the truncation of decimals without rounding.

These newfound skills will undoubtedly prove useful in your Excel journey. By mastering the art of rounding, you can confidently perform calculations, analyze data more accurately, and present information in a polished and professional manner.

With practice, you will become a true expert in using Excel’s INT function to your advantage. In conclusion, mastering Excel’s INT function is key to efficiently rounding numbers and manipulating decimal values.

By understanding the syntax and arguments, you can easily round down or remove the decimal portion using this powerful tool. Additionally, the INT function can be combined with subtraction or the MOD function to obtain decimal values, further expanding its usefulness.

Remember to consider the alternative TRUNC function for specific rounding needs. With these skills, you can confidently perform calculations and present data accurately.

So, embrace the power of the INT function and excel in your Excel endeavors!
