  2. Shift operator - Wikipedia

    en.wikipedia.org/wiki/Shift_operator

    In time series analysis, the shift operator is called the lag operator. Shift operators are examples of linear operators, important for their simplicity and natural occurrence. The shift operator action on functions of a real variable plays an important role in harmonic analysis, for example, it appears in the definitions of almost periodic ...

  3. Bitwise operations in C - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operations_in_C

    The symbol of right shift operator is >>. For its operation, it requires two operands. It shifts each bit in its left operand to the right. The number following the operator decides the number of places the bits are shifted (i.e. the right operand). Thus by doing ch >> 3 all the bits will be shifted to the right by three places and so on.

  4. Arithmetic shift - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_shift

    In computer programming, an arithmetic shift is a shift operator, sometimes termed a signed shift (though it is not restricted to signed operands). The two basic types are the arithmetic left shift and the arithmetic right shift .

  5. 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.)

  6. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    More details of Java shift operators: [10] The operators << (left shift), >> (signed right shift), and >>> (unsigned right shift) are called the shift operators. The type of the shift expression is the promoted type of the left-hand operand. For example, aByte >>> 2 is equivalent to ((int) aByte) >>> 2.

  7. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    Operators that are in the same cell (there may be several rows of operators listed in a cell) are grouped with the same precedence, in the given direction. An operator's precedence is unaffected by overloading. The syntax of expressions in C and C++ is specified by a phrase structure grammar. [7] The table given here has been inferred from the ...

  8. 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

  9. Composition operator - Wikipedia

    en.wikipedia.org/wiki/Composition_operator

    When the transfer operator is a left-shift operator, the Koopman operator, as its adjoint, can be taken to be the right-shift operator. An appropriate basis, explicitly manifesting the shift, can often be found in the orthogonal polynomials. When these are orthogonal on the real number line, the shift is given by the Jacobi operator.
