Floating point math? I thought, historically at least, that bc is built
on dc (arbitrary precision integer math, reverse polish syntax) and that
consequently bc uses fixed point math rather than floating point.

The only problem is, how do you send a message from Earth to Mars
instantly? Does anyone have any ideas about where we can start?
John Baez <baez at math.mit.edu>:
Just use a coordinate system in which the point at which the message is
received has the same t coordinate as the point at which the message was sent.
