Turned out that the comment was not aligning with the behavior of `Double.parseDouble("")`, as it throws `NumberFormatException` (Thanks to @LanceAndersen who let me know). So how about changing it to:

If (count == 0) this returns 0.0, unlike Double.parseDouble("") which throws NumberFormatException

It also applies to `getLong()`, and you may want to add comments `getBigDecimal()` for consistency with other `getXXX()` methods (without "unlike ..." part though).
