  2. Arithmetic shift - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_shift

    The two basic types are the arithmetic left shift and the arithmetic right shift. For binary numbers it is a bitwise operation that shifts all of the bits of its operand; every bit in the operand is simply moved a given number of bit positions, and the vacant bit-positions are filled in.

  3. Shift operator - Wikipedia

    en.wikipedia.org/wiki/Shift_operator

    ⁠ The shift operator acting on functions of a real variable is a unitary operator on ⁠ (). In both cases, the (left) shift operator satisfies the following commutation relation with the Fourier transform: F T t = M t F , {\displaystyle {\mathcal {F}}T^{t}=M^{t}{\mathcal {F}},} where M t is the multiplication operator by exp( itx ) .

  4. Bit array - Wikipedia

    en.wikipedia.org/wiki/Bit_array

    To obtain the bit mask needed for these operations, we can use a bit shift operator to shift the number 1 to the left by the appropriate number of places, as well as bitwise negation if necessary. Given two bit arrays of the same size representing sets, we can compute their union , intersection , and set-theoretic difference using n / w simple ...

  5. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    Java adds the operator ">>>" to perform logical right shifts, but since the logical and arithmetic left-shift operations are identical for signed integer, there is no "<<<" operator in Java. More details of Java shift operators: [10] The operators << (left shift), >> (signed right shift), and >>> (unsigned right shift) are called the shift ...

  6. Bitwise operations in C - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operations_in_C

    The symbol of left shift operator is <<. It shifts each bit in its left-hand operand to the left by the number of positions indicated by the right-hand operand. It works opposite to that of right shift operator. Thus by doing ch << 1 in the above example (11100101) we have 11001010. Blank spaces generated are filled up by zeroes as above.
