        int result;

        value = 4;
        result = Math.Sign(value);
        Console.WriteLine($"Sign({value}) = {result}");

        value = -4;
        result = Math.Sign(value);
        Console.WriteLine($"Sign({value}) = {result}");
    }
}

Output

Sign(4) = 1
Sign(-4) = -1

Sign(Int32)

Math.Sign(value) returns an integer that indicates the sign of a 32-bit signed integer value.
