After performing a floating point addition, it is desired to normalize the sum; that is, shift the most significant digit of the mantissa into the left-most digit location, and adjust the exponent accordingly. Prior art techniques required performing the addition before calculating the number of shifts required. The present technique determines an approximate shift from the addends during addition, resulting in a significant time saving.
