Performs a bit shifting operation.

BitShift ( value, shift )

shift | Number of bits to shift to the right (negative numbers shift left).

Bemerkungen

Remember hex notation can be used for numbers.
Left shifts are equivalent to halving; right shifts to doubling.

Beispiel

$x = BitShift(14, 2)
; x == 3 because 1110b right-shifted twice is 11b == 3
$y = BitShift(14, -2)
; y == 48 because 1110b left-shifted twice is 111000b == 56
$z = BitShift( 1, -31)
; z == -2147483648 because in 2's-complement notation, the
; 32nd digit from the right has a negative sign.
