The format is design by the person who created extract script, it has
nothing to do with the library itself.
The actual number is irrelevent, it's the spacing that's important. I
extended the script so that if you prefix it by an "!" it becomes a

These are normal scientific notation number. The standard
text-to-float conversion should be able to read it just fine. It
doesn't have to be exactly that format by the way, just about any
number format will do.
This marks the end of a polygon.

Currently you can't omit the begin and end markers. Not sure why we
should make it possible either...
Don't worry about java.txt.Decimal, just use whatever you normally use
for printing numbers.
