JesterXL (Dec 01 2022 at 16:24): JesterXL (Dec 01 2022 at 16:24):How do I convert a Str to a Num? I see various F64 and Nat's, but not sure how to get a Nat to an Int or Num.
JesterXL (Dec 01 2022 at 16:27):Oh wait, disregard, this worked Str.toNat "10" |> Result.map \value -> value + 1
JesterXL (Dec 01 2022 at 16:27):I guess I can treat Nat as an Int, ya? Helpful.
Ayaz Hafiz (Dec 01 2022 at 16:35):There are a large number of Str -> Num methods of the form toI8, toI16, etc: https://www.roc-lang.org/builtins/Num#toI8
Ayaz Hafiz (Dec 01 2022 at 16:36):There's nothing that goes from Str -> Num * though - you have to parse into a concrete number type
