Bit32.lrotate

Available since: Gideros 2022.3
Class: bit32

Description

Returns a number after its bits have been rotated to the left by a given number of times.

(number) = bit32.lrotate(x,disp)

Returns the number x rotated disp bits to the left.

The number disp may be any representable integer. For any valid displacement, the following identity holds:

assert(bit32.lrotate(x, disp) == bit32.lrotate(x, disp % 32))
Negative displacements rotate to the right

Parameters

x: (number) value
disp: (number) displacement

Return values

Returns (number) result after bits left rotation
