Use the ISEVEN function to check if a numeric value is an even number. ISEVEN will return TRUE when a numeric value is even and FALSE when a numeric value is odd. If value is not numeric, ISEVEN will return the #VALUE error.
For example, =ISEVEN(A1) will return TRUE if A1 contains the number 2 and FALSE if A1 contains the number 3.
Usually, value is supplied as a cell address.
ISEVEN is part of a group of functions called the IS functions that all return the logical values TRUE or FALSE.
