Subtracts two arrays element-wise.
Arguments
- lhs, rhs
(
arrayish)
Two inputs of the same data type and shape. Can be any numeric data type. R values take the other operand's data type when it is in their data type category, and their default data type when neither operand has one. An R value outside the other operand's category is an error, as are two R values of different storage types.
Value
(arrayish)
Has the inputs' shape and data type.
StableHLO
Lowers to hlo_subtract(), specified under

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{} ]
