  2. Arithmetic shift - Wikipedia

    en.wikipedia.org/wiki/Arithmetic_shift

    The formal definition of an arithmetic shift, from Federal Standard 1037C is that it is: . A shift, applied to the representation of a number in a fixed radix numeration system and in a fixed-point representation system, and in which only the characters representing the fixed-point part of the number are moved.

  3. Right rotation - Wikipedia

    en.wikipedia.org/wiki/Right_rotation

    In a binary search tree, a right rotation is the movement of a node, X, down to the right.This rotation assumes that X has a left child (or subtree). X's left child, R, becomes X's parent node and R's right child becomes X's new left child.

  4. Bitwise operation - Wikipedia

    en.wikipedia.org/wiki/Bitwise_operation

    In computer programming, a bitwise operation operates on a bit string, a bit array or a binary numeral (considered as a bit string) at the level of its individual bits.It is a fast and simple action, basic to the higher-level arithmetic operations and directly supported by the processor.

  5. 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.

    Rotate right by immediate without affecting flags. SARX ra,r/m,rb: VEX.LZ.F3.0F38 F7 /r: Arithmetic shift right without updating flags. For SARX, SHRX and SHLX, the shift-amount specified in rb is masked to 5 bits for 32-bit operand size and 6 bits for 64-bit operand size. SHRX ra,r/m,rb: VEX.LZ.F2.0F38 F7 /r: Logical shift right without ...

  7. Logical shift - Wikipedia

    en.wikipedia.org/wiki/Logical_shift

    Shifting right by n bits on an unsigned binary number has the effect of dividing it by 2 n (rounding towards 0). 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 >>.

  8. Tree rotation - Wikipedia

    en.wikipedia.org/wiki/Tree_rotation

    Notice that the right child of a left child of the root of a sub-tree (for example node B in the diagram for the tree rooted at Q) can become the left child of the root, that itself becomes the right child of the "new" root in the rotated sub-tree, without violating either of those constraints. As seen in the diagram, the order of the leaves ...

  9. Binary number - Wikipedia

    en.wikipedia.org/wiki/Binary_number

    The binary representations in Pingala's system increases towards the right, and not to the left like in the binary numbers of the modern positional notation. [13] In Pingala's system, the numbers start from number one, and not zero. Four short syllables "0000" is the first pattern and corresponds to the value one.
