whitequark: re. FP numbers for time, a ~classic solution (used in particular in SOFA/ERFA) is double-double
egg|anbo|egg is now known as egg_
egg_ is now known as egg|laptop|egg
<whitequark>
right but
<whitequark>
like i had no excuse for using an integer number of picoseconds, personally
<whitequark>
i didn't do it because i was a dumbass
<whitequark>
js has it considerably harder
<egg|laptop|egg>
right; using FP everywhere is convenient even when integer arithmetic is available though, as soon as you start doing exotic things like multiplication (or fancier) to your time intervals, hence the usefulness for astronomy
<whitequark>
the problem here is that i actually want my intervals to be exact
<whitequark>
and, well, people run things at 30 MHz

whitequark: yeah, discrete things have requirements that differ from physicsy things
