WebAug 16, 2024 · The unsigned modifier keyword specifies an unsigned representation that can only hold non-negative values. A size modifier specifies the width in bits of the integer representation used. The language supports short, long, and long long modifiers. A short type must be at least 16 bits wide. Web4. Bitwise AND your integer with the mask having exactly those bits set that you want to extract. Then shift the result right to reposition the extracted bits if desired. unsigned int lowest_17_bits = myuint32 & 0x1FFFF; unsigned int highest_17_bits = (myuint32 & (0x1FFFF << (32 - 17))) >> (32 - 17);
