Specifies the constant value that is formatted with the specified bus type.
The number format of the bus.
Specifies the number of bits to the left of the binary point, including the
sign bit. This parameter does not apply to single-bit buses.
Specifies the number of bits to the right of the binary point. This parameter
applies only to signed fractional buses.
