WebAug 8, 2015 · (Note that you can of course implement subtraction, very tediously, using bitwise logical operations.) In essence, if you're doing Q = N/D: 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. WebLogical operators operates on boolean expressions ( true and false) and returns boolean values. Logical operators are used in decision making and loops. Here is how the result is evaluated for logical AND and OR operators. In simple words, the table can be summarized as: If one of the operand is true, the OR operator will evaluate it to true.
