WebHowever, a shift cannot reclaim "lost" bits. For example, if we shift this pattern: 00111000 00000000 00000000 00000110 to the left 4 positions (939,524,102 << 4), we get 2,147,483,744: ... Bit shifting is often used in low-level graphics programming. For … WebRemarks. Shifting a number right is equivalent to removing digits from the rightmost side of the binary representation of the number. For example, a 2-bit shift to the right on the decimal value 13 converts its binary value (1101) to 11, or 3 in decimal.
