  2. 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 ) .

  3. Arithmetic shift - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_shift

    The (1999) ISO standard for the programming language C defines the right shift operator in terms of divisions by powers of 2. [11] Because of the above-stated non-equivalence, the standard explicitly excludes from that definition the right shifts of signed numbers that have negative values.

  4. 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 ...

  5. 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.

  6. Delimited continuation - Wikipedia

    en.wikipedia.org/wiki/Delimited_continuation

    Various operators for delimited continuations have been proposed in the research literature. [8]One independent proposal [5] is based on continuation-passing style (CPS) -- i.e., not on continuation frames—and offers two control operators, shift and reset, that give rise to static rather than to dynamic delimited continuations. [9]

  7. Unitary operator - Wikipedia

    en.wikipedia.org/wiki/Unitary_operator

    They are the unitary operators on R n. The bilateral shift on the sequence space ℓ 2 indexed by the integers is unitary. The unilateral shift (right shift) is an isometry; its conjugate (left shift) is a coisometry. Unitary operators are used in unitary representations. A unitary element is a generalization of a

  8. Translation operator (quantum mechanics) - Wikipedia

    en.wikipedia.org/wiki/Translation_operator...

    In quantum mechanics, a translation operator is defined as an operator which shifts particles and fields by a certain amount in a certain direction. It is a special case of the shift operator from functional analysis.

  9. Logical shift - Wikipedia

    en.wikipedia.org/wiki/Logical_shift

    Logical right shift differs from arithmetic right shift. Thus, many languages have different operators for them. For example, in Java and JavaScript, the logical right shift operator is >>>, but the arithmetic right shift operator is >>. (Java has only one left shift operator (<<), because left shift via logic and arithmetic have the same effect.)
