Devoluciones

Int32

Número que indica el signo de value, como se muestra en la tabla siguiente.

Valor devuelto	Significado
-1	`value` es menor que cero.
0	`value` es igual a cero.
1	`value` es mayor que cero.

Ejemplos

En el ejemplo siguiente se muestra cómo usar el método Sign(Int32) para determinar el signo de un valor de Int32 y mostrarlo en la consola.
