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).
