--- Comment #3 from Sophie <[email protected]> --- It's a missing value, but in the case of numeric types a missing value is simply one example of a malformed value. I think the better approach in the code you used as an example would be to not expect the CSV logic to handle malformed floats. Use the CSV parser to extract strings, and then your code should assume responsibility for validating and handling malformed inputs. --
