    Implement specialBits()
    
    Because 0xffca3fff has exactly 1 byte 0b00101000
    in the middle, use its complement 0b11010111 to
    shift left 14 bits and complemet it finally.

    Fix shifting warnings from cppcheck
    
    Because cppcheck will complain when shifting signed 32-bit
    value by 31 bits, this commit change these variables that
    needs to shift 31 bits to become unsigned and add the
    integer-suffix 'u' to integer constants.
    For example:
    `x >> 31` becomes `(unsigned) x >> 31`
    `1 >> 31` becomes `1u >> 31`
