Primitive Subtraction

Subtracts two arrays element-wise.

Usage

prim_sub(lhs, rhs)

Arguments

lhs, rhs

(arrayish)
Two inputs of the same data type and shape. Can be any numeric data type. R values assume the other operand's data type when it is in their data type category, and their default data type when neither operand has one.

Value

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

Examples

# two R values: both take an R double's default data type
prim_sub(5, 3)
#> AnvlArray
#>  2
#> [ CPUf32{} ] 

# the R value is built at the array's data type instead
prim_sub(5, nv_scalar(3, "f64"))
#> AnvlArray
#>  2
#> [ CPUf64{} ]
