shift

Usage

shift(a, n)
shift!(a, n)

Signature

shift:

(%, MachineInteger) $\to$ %

Parameter	Type	Description
a	%	an integer
n	MachineInteger	a machine integer

Returns

Returns $a$ shifted left $n$ times if $n \ge 0$, shifted right $-n$ times if $n \le 0$.

Remarks

shift! does not make a copy of $x$, which is therefore modified after the call. It is unsafe to use the variable $x$ after the call, unless it has been assigned to the result of the call, as in x := shift!(x, n).
