All,
To celebrate the list working again, I'll pass along something that brought a smile to my face a bit ago. I was looking at help for kcalc, and I noticed a entry for long-double precision and clicked it:

Remember when user-choice and customization was the touchstone of Linux? Back when the help pages told you about defines to tailor the app to your needs and then a simple:
./configure make make install
The good ole days.... :)
Ordinarily I hesitate to ask silly questions, but when was the last time you needed double precision calculation, much less long double? Never mind it's not even a IEEE standard..
Yet the processor has those types,, I assue so someone uses them.
Yeah, if you are working, for example, at places like CERN or LIGO.
Precisely! /* estimate the solar declination angle (in radians) */ sp.decl = 0.006918 - 0.399912 * cos(sp.fracyr) + 0.070257 * sin(sp.fracyr) - 0.006758 * cos(2 * sp.fracyr) + 0.000907 * sin(2 * sp.fracyr) - 0.002697 * cos(3 * sp.fracyr) + 0.00148 * sin(3 * sp.fracyr); -- David C. Rankin, J.D.,P.E.
