ISEVEN function

PRO BASIC

The ISEVEN function in Jspreadsheet Formulas Pro is a simple tool that allows you to determine if a number is even. When you input a number into this function, it will analyze it and return a value of TRUE if the number is even. Conversely, if the number is odd, the function will return a FALSE value. This can be useful when sorting data or performing calculations that require knowledge of whether a number is even or odd.

Documentation

Checks if a given number is even and returns TRUE if the number is even, and FALSE otherwise.

Syntax

ISEVEN(num)

Parameter	Description
`num`	The number that you want to test.

Behavior

The ISEVEN function checks if a given number is even or not. It returns 'TRUE' if the number is even, and 'FALSE' if it is odd. Here's how it behaves with different inputs:

Numbers: The function works as expected with numeric inputs. For example, ISEVEN(2) would return TRUE, while ISEVEN(3) would return FALSE.
Empty cells: If the reference cell is empty, the function will return #VALUE! error.
Text: If the input is a text, the function will return #VALUE! error.
Booleans: If the input is a Boolean value, it'll be interpreted as 1 for TRUE and 0 for FALSE and then checked for evenness.
Errors: If the reference cell has an error, the 'ISEVEN' function will also return that same error.

Common Errors

Error	Description
#VALUE!	This error occurs when the input or the reference cell is not a number or is empty.
#REF!	This error is returned when the input is a reference that doesn't point to a cell or an array.

Best practices

Always ensure that the input or the reference cell contains a numeric value to avoid #VALUE! errors.

Be aware that 'ISEVEN' interprets Boolean values as 1 for TRUE and 0 for FALSE. If you want to check the evenness of the actual Boolean value, convert them to numbers first.

While using cell references as an argument for 'ISEVEN', ensure that the referenced cell is not prone to errors or empty, as 'ISEVEN' will propagate the same error.

'ISEVEN' function only considers the integer part of the number to determine its evenness. So, numbers like 2.1 or 2.9 are still considered even.

Usage

A few examples using the ISEVEN function.

ISEVEN(2) returns TRUE because 2 is even  
ISEVEN(-4) returns TRUE because -4 is even  
ISEVEN(B3) returns TRUE if cell B3 contains an even number.
