public:
 static int Sign(short value);

public static int Sign (short value);

static member Sign : int16 -> int

Public Shared Function Sign (value As Short) As Integer

매개 변수

value: Int16

부호 있는 숫자입니다.

반환

Int32

다음 표와 같이 value기호를 나타내는 숫자입니다.

반환 값	의미
-1	`value` 0보다 작습니다.
0	`value` 0과 같습니다.
1	`value` 0보다 큽니다.
