> These conversions can be performing better. If the input is not numeric
> (1234abcd) the code calls Double.valueOf(String) regardless before finally
> returning null. Any script that inadvertently (user's mistake or not) tries
> to cast non-numeric column to int or long would result in many wasteful
> calls.
> We can avoid this and only handle the cases we find the input to be a decimal
> number (1234.56) and return null otherwise even before trying
> Double.valueOf(String).
