Supply multiple methods. Copy. A value of a constant expression of type int (for example, a value represented by an integer literal) can be implicitly converted to sbyte, byte, short, ushort, uint, ulong, nint, or nuint, if it's within the range of the destination type: As the preceding example shows, if the constant value is not within the range of the destination type, a compiler error CS0031 occurs. they're always integers), so one can special case such large numbers to just return themselves.
