この関数は Google スプレッドシートでも Excel と同じように機能します。構文も引数も同じです。
ISODD(number)The ISODD function evaluates a numeric value and returns TRUE if the number is odd, or FALSE if it is even. If the provided argument is not an integer, it is truncated toward zero before the check is performed.
=ISODD(3)結果: TRUE
3 is an odd number.
=ISODD(4.5)結果: FALSE
4.5 is truncated to 4, which is an even number.
The function will return a #VALUE! error if the input cannot be converted to a number.
