[time-nuts] arduino solar clock

[Chris Albertson]

It is.  Both "double" and "float" are 32-bits.  Arduino uses the GCC AVR
compiler.

If you care a lot about precision you use integer math and do all your
calculations in integer units of milli or microseconds.  If you try to keep
time in "floats" you are working with about four decimal digit
approximations which might not be good enough.
