Shift Left

Element-wise left bit shift.

Usage

nv_shift_left(x, shift)

Arguments

x

(arrayish)
The array whose bits are shifted. Can be any integer data type.

shift

(arrayish)
By how many bits to shift each element of x. Brought to x's data type, which it must fit in. Scalars are broadcast.

Value

(arrayish)
Has the inputs' broadcast shape and x's data type.

See also

prim_shift_left() for the underlying primitive.

Examples

x <- nv_array(c(1L, 2L, 4L))
shift <- nv_array(c(1L, 2L, 1L))
nv_shift_left(x, shift)
#> AnvlArray
#>  2
#>  8
#>  8
#> [ CPUi32{3} ] 

# the result keeps `x`'s data type, which `shift` is brought to
nv_shift_left(nv_scalar(8L, "i64"), nv_scalar(2L, "i32"))
#> AnvlArray
#>  32
#> [ CPUi64{} ] 

# a scalar is broadcast
nv_shift_left(x, 1L)
#> AnvlArray
#>  2
#>  4
#>  8
#> [ CPUi32{3} ]
