Right most set bit mask
WebOct 31, 2024 · You can think of left-shifting by b as multiplication by 2b and right-shifting as integer division by 2b. The most common use for shifting is to access a particular bit, for example, 1 << x is a binary number with bit x set and the others clear (bits are almost always counted from the right-most/least-significant bit, which is numbered 0). WebAug 5, 2024 · To achieve this, 1 is used as the bit mask (to determine whether the first bit or rightmost bit is set). For integers, the least significant bit (first bit or rightmost bit) can be used to determine whether the number is even or odd. If the least significant bit is turned on (set to 1 ), the number is odd; otherwise, the number is even.
