This functions performs a logical right shift on the integer value by integer n positions. In a logical shift, zeros are shifted in to replace the discarded bits. See Bitwise operation for more details.

Syntax

int bitRShift ( int value, int n )

Required arguments

  • value: The value you want to perform the shift on.
  • n: The amount of positions to shift the value by.

Returns

Returns the logical right shifted value as integer.

Example

This example shows the usage of the function bitRShift.

local value = 0xFFFFFFFF -- binary: 1111 1111 1111 1111 1111 1111 1111 1111, decimal: 4.294.967.295
local positions = 0x4 -- binary: 0100, decimal: 4
local shifted = bitRShift( value, positions ) -- binary: 0000 1111 1111 1111 1111 1111 1111 1111, decimal: 26.8435.455

-- Comparsion:
-- binary: 1111 1111 1111 1111 1111 1111 1111 1111, decimal: 4.294.967.295
-- binary: 0000 1111 1111 1111 1111 1111 1111 1111, decimal: 26.8435.455
