In other words, the result is equivalent to the result of copying each bit in binary representation of input "value" to its left position, to the number of times specified by the value of the input "Shift, bit". Thus, least significant (right-most) bit in the binary representation each time will have a value equal to the outgoing (most significant, extending to the left) bit of input value.

Иными словами, результат эквивалентен результату операции копирования каждого бита в двоичном представлении входа «Значение» в позицию справа от него, произведенной число раз, заданное значением входа «Сдвиг, бит». При этом старший (самый левый) бит в двоичном представлении результата каждый раз получает значение, равное уходящему (самому младшему, выдвигаемому вправо) биту входного значения.

Circular shift to the right. Set the output result as the logical right shift in binary representation of the input "Value", the number of bits to shift specified by the input "Shift, bits", while leaving bit appears in place of free pop spot on the other end of the number.


In other words, the result is equivalent to the result of copying each bit in binary representation of input "value" to its right position, to the number of times specified by the value of the input "Shift, bits". Thus, the most significant (left-most) bit in the binary representation each time will have a value equal to the outgoing (least significant, extending to the right) bit of input value.

For example:

Value = 51000 = 0xC738 = 0b1100011100111000
Shift, bits = 2
Result = 12750 = 0x31CE = 0b0011000111001110

Features

Circular shift of 16-bit value in either direction for 8-bit, reverses its upper and lower bytes.
