Element-wise bitwise AND – a logical AND on a boolean input, and a bit-by-bit one on an integer. You can also use the & operator, which expects bool inputs, however.

Usage

nv_and(lhs, rhs)

# S3 method for class 'AnvlArray'
e1 & e2

Arguments

lhs, rhs

(arrayish)
Two inputs with a common data type. Can be any integerish data type. Scalars are broadcast. An R value takes the other operand's data type when that is in its own or a higher category. Otherwise it settles on its default data type, and the operands meet at their common data type.

e1, e2

(arrayish)
The operands of the operator, which it passes on as lhs and rhs.

Value

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

The & operator

& is logical, like in base R. Unlike base R it only accepts booleans and does not auto-convert non-booleans by comparing them with 0.

See also

prim_and() for the underlying primitive.

Examples

x <- nv_array(c(TRUE, FALSE, TRUE))
y <- nv_array(c(TRUE, TRUE, FALSE))
x & y
#> AnvlArray
#>  1
#>  0
#>  0
#> [ CPUbool{3} ] 

# different data types are promoted to their common one
nv_and(nv_scalar(12L, "i32"), nv_scalar(10L, "i64"))
#> AnvlArray
#>  8
#> [ CPUi64{} ] 

# a scalar is broadcast
x & TRUE
#> AnvlArray
#>  1
#>  0
#>  1
#> [ CPUbool{3} ]
