BitLShift

This functions performs a logical left 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 bitLShift ( 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 left shifted value as integer.

Example

This example shows the usage of the function bitLShift.

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 = bitLShift( value, positions ) -- binary: 1111 1111 1111 1111 1111 1111 1111 0000, decimal: 4.294.967.280

-- Comparsion:
-- binary: 1111 1111 1111 1111 1111 1111 1111 1111, decimal: 4.294.967.295
-- binary: 1111 1111 1111 1111 1111 1111 1111 0000, decimal: 4.294.967.280
