WebJan 24, 2024 · Bits that are shifted off the end of the binary number are lost forever. The bitwise right shift (>>) operator shifts bits to the right. 1100 >> 1 is 0110. 1100 >> 2 is 0011. 1100 >> 3 is 0001. Note that in the third case we shifted a bit off the right end of the number, so it is lost. WebLeft shift operator is a bitwise shift operator in C which operates on bits.

Such as: float f = 128; f = (float) ( ( (int) f) << 1 ); And in the above, f should be 256.0. Now obviously this is problematic if you start with 128.4 as the cast will drop the .4. You may not want to be using a float in first place. Share.
