# MOD function

Excel MOD Function is a mathematical function used to find the remainder when one number is divided by another. It can be a helpful tool for various applications, such as calculating cyclic patterns or distributing items evenly.

## Syntax

MOD(number, divisor)

## How to Use

To use the Excel MOD function, follow the syntax: MOD(number, divisor). Here are some examples to illustrate its use:

Example 1: Finding the Remainder

In this example, MOD(17, 5) returns 2 because when you divide 17 by 5, you have a remainder of 2.

Example 2: Handling Negative Numbers

Even with negative numbers, MOD(-10, 3) will return 2, as it still calculates the remainder.

Example 3: Handling Fractions

MOD(11.5, 3) returns 2.5, as it can handle decimal numbers and provide the remainder.

Example 4: Handling Zero Divisor

If you attempt to divide by 0, Excel will return a #NUM! error, as division by zero is undefined.

Example 5: Using MOD in Conditional Formatting

You can use MOD in Excel’s Conditional Formatting to create alternating row colors in a table. For instance:

This formula will format every other row with a different color, creating a striped pattern.

## Additional Information

MOD is a versatile function for calculating remainders. It can be particularly useful in scenarios like scheduling, where you need to distribute tasks evenly or in cyclic patterns.
