Promote arrays to a common data type, see promotion_common() for more details.

Usage

nv_promote_to_common(...)

Arguments

...

(arrayish)
Values to promote.

Value

(list() of arrayish)
The inputs, each at their common data type and with its own shape.

Examples

# An integer is promoted to float
x <- nv_scalar(1, dtype = "f32")
y <- nv_scalar(1L, dtype = "i32")
nv_promote_to_common(x, y)
#> [[1]]
#> AnvlArray
#>  1
#> [ CPUf32{} ] 
#> 
#> [[2]]
#> AnvlArray
#>  1
#> [ CPUf32{} ] 
#> 
# an R value yields to the data type it meets within its category
with_default_dtypes(c(float = "f64"), nv_promote_to_common(1, x))
#> [[1]]
#> AnvlArray
#>  1
#> [ CPUf32{} ] 
#> 
#> [[2]]
#> AnvlArray
#>  1
#> [ CPUf32{} ] 
#> 
# and settles on its default otherwise
with_default_dtypes(c(float = "f64"), nv_promote_to_common(1, y))
#> [[1]]
#> AnvlArray
#>  1
#> [ CPUf64{} ] 
#> 
#> [[2]]
#> AnvlArray
