Sign(Single)

Gibt eine ganze Zahl zurück, die das Vorzeichen einer Gleitkommazahl mit einfacher Genauigkeit angibt.Returns an integer that indicates the sign of a single-precision floating-point number.

public:
 static int Sign(float value);

public static int Sign (float value);

static member Sign : single -> int

Public Shared Function Sign (value As Single) As Integer

Parameter

value: Single

Eine Zahl mit Vorzeichen.A signed number.

Gibt zurück

Int32

Eine Zahl, die das Vorzeichen von value angibt, wie in der folgenden Tabelle veranschaulicht.A number that indicates the sign of value, as shown in the following table.

RückgabewertReturn value	BedeutungMeaning
-1-1	`value` ist kleiner als Null.`value` is less than zero.
00	`value` ist gleich 0 (null).`value` is equal to zero.
11	`value` ist größer als 0 (null).`value` is greater than zero.

Ausnahmen

ArithmeticException

value ist gleich NaN.value is equal to NaN.

Beispiele

Im folgenden Beispiel wird veranschaulicht, wie die Sign(Single) -Methode verwendet wird, um das Vorzeichen eines Werts zu bestimmen Single und in der Konsole anzuzeigen.The following example demonstrates how to use the Sign(Single) method to determine the sign of a Single value and display it to the console.
