A sticky bit value of the product of mantissas X and Y is predicted by a circuit that comprises a bit pattern generation circuit 25A that generates a bit pattern B, based on a trailing zero bit pattern of the multiplier Y, having all values of the sticky bit S corresponding to any number C of the trailing 0s of the multiplicand X; a priority encoder 21 for providing the number C depending on X; and a sticky bit selection circuit 26A for selecting one bit in the bit pattern B as a value of the sticky bit S depending on the value C.
