# How to Round Numbers to ODD or EVEN in Excel

Welcome to this guide on rounding numbers using the EVEN and ODD functions in Excel. Rounding numbers can be a useful tool in data analysis and spreadsheet organization.

The EVEN and ODD functions in Excel allow for quick and easy rounding of numbers to the nearest even or odd number. This guide will walk you through the steps of using these functions, as well as the ISEVEN and ISODD functions, to round and categorize your data in Excel.

Rounding numbers to the nearest even number. In this example, we have a list of numbers. We want to find out the nearest even number of each item. To do this, we will use the EVEN function. The EVEN function will round up the number to the nearest even whole number.

First, we select the cell that we want the rounded-up number to appear in, and then we input =EVEN(A2). Copy and paste this formula into all the other cells you want to apply it to.

Note: Excel will round up numbers to the nearest whole number. In the example, the number in A2 (42.08) is a mixed decimal number and not a whole number. As a result, Excel must round UP the number to a whole number: 44. The same applies when using the ODD function.

Rounding numbers to the nearest odd number. In the same example, we want to find the nearest odd whole number. To do this, we will use the ODD function. This function works similarly to the EVEN function, but instead of rounding up to the nearest even number, it will round up to the nearest odd number.

First, we select the cell that we want the rounded-up number to appear in, and then we input =ODD(A2). Copy and paste this formula into all the other cells you want to apply it to.

Using the ISEVEN and ISODD Functions. In the same example, we want to figure out if the list of numbers is even or odd. To do this, we will use the ISEVEN and ISODD functions. These functions return a TRUE or FALSE value, allowing you to quickly and easily sort and analyze your data.

1. Type =ISEVEN(number) or =ISODD(number) in the cell, replacing “number” with the cell reference or number you want to check.
2. Press Enter to apply the function. The cell will now display TRUE if the number is even (for ISEVEN) or odd (for ISODD), and FALSE if the number is not.
3. To apply the function to multiple cells, you can use the fill handle to copy the formula to the desired range of cells.

Note: Unlike the EVEN and ODD functions, the ISEVEN and ISODD functions will convert the numbers to their whole numbers. (E.g., 42.08 is converted into 42.)

Using Conditional Formatting. An alternative to using the ISEVEN and ISODD functions in Excel is to use the conditional formatting feature. This allows you to apply formatting, such as color or font style, to cells based on certain conditions, such as whether a number is even or odd.

Here is a step-by-step guide on how to use conditional formatting to identify even and odd numbers:

1. Select the range of cells that you want to format.
2. Go to the Home tab and click on the Conditional Formatting button.
3. Select “New Rule” from the drop-down menu. 4. In the “New Formatting Rule” window, select “Use a formula to determine which cells to format”. 5. In the “Format values where this formula is true” field, enter the formula for identifying even numbers: =ISEVEN(A2) (assuming A2 is the first cell in the selected range). Select a format to apply to the even numbers (e.g. fill color) 6. Click on “OK” to apply the formatting. 7. You will now see that even numbers are formatted differently than odd numbers. By using conditional formatting, you can quickly and easily identify even and odd numbers in your data and make better use of your spreadsheet.

## Conclusion

Understanding and utilizing these functions and techniques can have a significant impact on your productivity and the effectiveness of your data analysis. By learning these tools and techniques, you can efficiently round and organize your data to make better use of your spreadsheet.
