WebAug 8, 2015 · Align the most-significant ones of N and D. Compute t = (N - D);. If (t >= 0), then set the least significant bit of Q to 1, and set N = t. Left-shift N by 1. Left-shift Q by 1. Go to step 2. Loop for as many output bits (including fractional) as you require, then apply a final shift to undo what you did in Step 1. WebThe Bitwise Complement. The bitwise complement operator, the tilde, ~, flips every bit. A useful way to remember this is that the tilde is sometimes called a twiddle, and the bitwise complement twiddles every bit: if you have a 1, it's a 0, and if you have a 0, it's a 1. 0, of course, is all 0s: 00000000 00000000.
