Wakerly, ISBN The exact answer depends on the value of n , and will be either 2 n e. Suppose a 3n-bit number B is represented by an n-digit octal number Q.
Cases 1 and 2 assume no overflow. Note that x m — 1 is the sign bit of Y. The value of Y is 0. Remaining half and remaining summation terms have shifted coefficients as specified.
The operation overflows if b n — 1 and b n — 2 have opposite values at the start of the operation. If there was a borrow, subtract 6 from the result and record a BCD borrow.
