## Summary

The Excel ISODD function returns TRUE when a value is an odd number, and FALSE when a value is an even number. ISODD will return the #VALUE error if a value is not numeric.

## Purpose

Test if a value is odd

## Return value

A logical value (TRUE or FALSE)

## Syntax

``=ISODD(value)``
• value - The numeric value to check.

## How to use

The ISODD function tests for odd numbers. ISODD takes one argument, value, which should be a numeric value or a cell reference. When value is an odd number, ISODD returns TRUE. When value is an even number, ISODD returns FALSE. If value is not numeric, ISODD will return the #VALUE error. Only the integer portion of value is evaluated, decimal values are truncated.

### Examples

The ISODD function returns TRUE or FALSE:

``````=ISODD(4) // returns FALSE
=ISODD(3) // returns TRUE
=ISODD(0) // returns FALSE
``````

If cell A1 contains 11, the formula below returns TRUE:

``````=ISODD(A1) //returns TRUE
``````

Only the integer portion of value is tested. If value is a decimal number, the decimal portion is truncated:

``````=ISODD(4.1) // returns FALSE
=ISODD(0.33) // returns FALSE
=ISODD(7.4) // returns TRUE
``````

### Notes

• If value is not numeric, ISODD will return the #VALUE error.
• Only the integer portion of value is tested; decimal values are truncated.
• Use the ISEVEN function to test for even numbers.
