Hi! Thank you for improving the project! I see you have forked it. Can you create a pull request, so I can apply your changes? If not, I will add these changes by myself reflecting your name in a commit description. My apologies for a late answer on the issue, I was very busy.

Sure. Also I added handling for the 'd' type. There is a parseDouble() but I did not used it as my projects use decimal most of the time. So I implemented a new parseDecimal(). Not sure if you can accept it.
