Hi everyone,
I've been doing some analysis of alternatives to using the JDK methods for 
parsing and writing floats and doubles.
See https://github.com/pjfanning/double-reader-writer for some numbers and 
links.

The results are pretty good. POI does a lot of double parsing (for example). It 
may not be worth the extra code complexity/maintenance, given the expensive 
work that POI has to do generally.

I'm not planning on making any POI changes but I'm just sharing the details, in 
case someone might have a use case that might be helped by using these 
alternatives.

Hopefully, the JDK teams will consider moving some of these more performant 
algorithms into the JDK itself.

Regards,
PJ
