datatable.FExpr.__rshift__()¶
Shift x
by y
bits to the right, i.e. x >> y
. Mathematically this
is equivalent to \(\lfloor x\cdot 2^{-y} \rfloor\).
If x
or y
are multi-column expressions, then they must have the
same number of columns, and the >>
operator will be applied to each
corresponding pair of columns. If either x
or y
are single-column
while the other is multi-column, then the single-column expression
will be repeated to the same number of columns as its opponent.
The left-shift operator can only be applied to integer columns, and the resulting column will have the same stype as its argument.
Parameters¶
x
,
y
FExpr
The arguments must be either FExpr
s, or expressions that can be
converted into FExpr
s.
return
FExpr
An expression that evaluates x >> y
.
