Because of the nature of binary numbers, for ever step shifting bits to the left doubles the number. As such you can express the same operation as 2 to the power number-of-shifts minus one: WebApr 2, 2024 · 19. If you are trying to change the bits in the floating-point representation, you could do something like this: union fp_bit_twiddler { float f; int i; } q; q.f = a; q.i &= (1 << 3); a = q.f; As AndreyT notes, accessing a union like this invokes undefined behavior, and the compiler could grow arms and strangle you.

WebDec 27, 2011 · 3. The >> operator is the same operator as it is in C and many other languages. A bitshift to the right. If your number is like this in binary: 0100 than it will be 0010 after >> 1. With >> 2 it will be 0001. So basically it's a nice way to divide your number by 2 (while flooring the remainder) ;) Share.
