Bitwise operation mask

WebMay 27, 2024 · 1) Clear all bits from LSB to ith bit mask = ~ ( (1 << i+1 ) - 1); x &= mask; Logic: To clear all bits from LSB to i-th bit, we have to AND x with mask having LSB to i-th bit 0. To obtain such mask, first left shift 1 i times. Now if we minus 1 from that, all the bits from 0 to i-1 become 1 and remaining bits become 0. WebAug 28, 2024 · A mask defines which bits you want to keep, and which bits you want to clear. Masking is the act of applying a mask to a value. This is accomplished by doing: …
