Wes McKinney commented on ARROW-1489:
-------------------------------------
Right, we might start with just the string-to-float "problem" — it probably
just means generating some array functions (with new names -- e.g. more
specifically, like "string_to_double") that do the errors-as-null behavior.
> [C++] Add casting option to set unsafe casts to null rather than some garbage
> value
