distance_to() method)
The distance_to()
The distance_to() method is a pretty standard great circle calculation,
and that's exactly its purpose. Are you sure your faster version does
the same? Does it yield the same (numeric) results? And besides, in the
visual range direct_distance_to() should be good enough, and it's
certainly
I've just spent a session optimizing performance of the weather dynamics
routines, and I have largely done so by analyzing the performance of
elementary Nasal function calls and making use of my findings (and also by
dispensing with the pretense of elegant coding).
I was rather gratified to see
