Element-wise bitwise NOT – a logical NOT on a boolean input, and a bit-by-bit one on an integer.

Usage

prim_not(x)

Arguments

x

(arrayish)
One input. Can be any integerish data type. An R value materializes at its default data type.

Examples

# on a boolean this is a logical negation
x <- nv_array(c(TRUE, FALSE, TRUE))
prim_not(x)
#> AnvlArray
#>  0
#>  1
#>  0
#> [ CPUbool{3} ] 

# on an integer it complements every bit, so `12L` becomes `-13`
prim_not(nv_array(12L))
#> AnvlArray
#>  -13
#> [ CPUi32{1} ]
