bofh: thinking back on that templatized approximate rootn question, it seems like a fun idea to have couple-of-sig-dec-correct, fistful-of-ULPs-errors, correctly-rounded, and exact versions of a bunch of things...
<egg|work|egg>
Principia has an exact product and an exact sum atm
<egg|work|egg>
why have one libm when you can have four
<bofh>
most of my libm-and-similar experience is in writing fistful-of-ULPs-errors code, b/c it is *hard* writing correctly-rounded Bessel functions of arbitrary order, even in the integer case.
<egg|work|egg>
bofh: right, but there is also a use case for the "rough approximation" version
<egg|work|egg>
(e.g. the stepsize adjustment of 0.9 * nth root of error estimate)
<bofh>
True, but oftentimes it suffices to inline like a truncated Taylor series in that case.
<egg|work|egg>
bofh: that seems a bit less readable than a dedicated function though
<egg|work|egg>
bofh: also why are there no search results for "a fistful of ULPs",
<bofh>
...I'm surprised, that's a very good turn-of-phrase. Clearly we need to fix this. :P

UmbralRaptor: Hyperion is just weird, and I think best ignored for these purposes, the rest of the Saturnian system seems far saner orbitally.

<SnoopJeDi> god I hope my advisor does not ever discover this paper <<< why?
<SnoopJeDi>
because he might like it
<SnoopJeDi>
the central motivation of the paper is basically identical to his: we have no sensible target energy scale beyond Higgs
<SnoopJeDi>
soooooo, go big or go home
<bofh>
SnoopJeDi: who says we'd find anything interesting even once we hit the Higgs energy scale, tho?
<SnoopJeDi>
This guy just out-crazied him by a remarkable margin
<SnoopJeDi>
bofh, well we've been past Higgs for decades, but...yea, that's basically the point
<SnoopJeDi>
most of the issues with Higgs detection weren't about production, we've surely been creating them since at *least* the Tevatron
<SnoopJeDi>
I mean I'm not a HEP guy but the perspective I have looking out is that people are looking to put dressing on building things like FCC after the fact
<SnoopJeDi>
NSAC made it priority uhh number 4 I think in the most recent long-range plan, after finishing FRIB (lol), continuing to operate CEBAF @ 12 GeV, and a ton-scale neutrinoless double-β decay. So basically the top of the list.
