If a non-whole number is input into the function, for example 13.5, the integral part will be considered:

ISODD(13.5) returns TRUE , because the function considers the integral part, which is 13.

If a non-numeric value is input into the function, it will return an error:

ISODD(“abc”) returns “#VALUE!”.
