Bit32.arshift
From GiderosMobile
Available since: Gideros 2022.3
Class: bit32
Description
Returns the number x shifted disp bits to the right. The number disp may be any representable integer. Negative displacements shift to the left.
(number) = bit32.arshift(x,disp)
This shift operation is what is called arithmetic shift. Vacant bits on the left are filled with copies of the higher bit of x; vacant bits on the right are filled with zeros. In particular, displacements with absolute values higher than 31 result in zero or 0xFFFFFFFF (all original bits are shifted out)
Parameters
x: (number) the number whose bits shall be shifted
disp: (number) the integer number of bits to shift by
Return values
Returns (number) result
