Good Evening,

First, the choice was not made by Ruby - you might want to do a little
homework in the future and see how the calculations are performed. Ruby (and
Python as far as I can see from their man pages) utilize the C standard for
trig calculations. This allows Ruby to simply wrap standard functions to
handle the calculations. Standards that are used in a very large and wide
variety of programs and languages. Because they are standards, it most
likely means an awful lot of thought went into them to decide the where and
when and how of accuracy.

Unfortunately, it seems that you have needs which go above and beyond the C
standard. Something like the GNU HPA (http://www.nongnu.org/hpalib/) might
be something you need an interface to (although it might not be any better
for you at the end of the day).

Your passion is admirable - but you have to understand that your pet project
doesn't always garner the attention of everyone. We all hate the corner
edges - but people are constantly trying to round (no pun intend) them off
as best they can. Things keep getting better every day and asking why
something exists as opposed to accusing the community of messing with you
will certainly help you in the long run.

John
