Implementing my first function (distance stuff) and notices that functions seem
to have a float bent to them. Not even sure what would be involved, but there
are cases for distance that I could see wanting double precision. Thoughts?

Float is almost never good enough. The loss of precision is horrific.

Are you saying it's not good enough for this case (the final answer of
a relative distance calculation)?
7 digits of precision is enough to

We have doubles already... It's just that our general purpose
Float is often OK until you try and use it for further calculation. Maybe it is
good enough for printing out distance, but maybe not for further use.

If I implement Vincenty's formula for distance between two points on an
ellipsoid that can be accurate down to the 0.5mm. Not doing that yet and not
planning on implementing, so this is not a huge issue right now.
Still, I think we should put it on our roadmap.
