| 2026-04-27 18:14:32 +0000 | <davean> | You have to start by articulating why the version is the same but smaller ... and now you've listed the cases ... |
| 2026-04-27 18:14:06 +0000 | <davean> | though the "making a small enough version" ... gets you very close to a proof ... |
| 2026-04-27 18:13:39 +0000 | <davean> | And often via paramatricity one can make a small enough version too |
| 2026-04-27 18:12:51 +0000 | <monochrom> | Yeah. |
| 2026-04-27 18:12:39 +0000 | <davean> | Lots of things *are* small enough |
| 2026-04-27 18:12:29 +0000 | <davean> | monochrom: I do think more things should be tested by enumeration. Its not an unreasonable strat. |

| 2026-04-27 18:04:28 +0000 | <EvanR> | not necessarily a good reason (AI) xD |
| 2026-04-27 18:04:11 +0000 | <davean> | and there is a reason its got that "NV" tacked on the front |
| 2026-04-27 18:04:00 +0000 | <davean> | There is a reason there is an NVFP4 |
| 2026-04-27 18:03:49 +0000 | <EvanR> | I'm sure eighth precision has some application somehow |
| 2026-04-27 18:02:58 +0000 | <davean> | EvanR: you're joking but I'm refering to actual datatypes |
| 2026-04-27 18:02:40 +0000 | <EvanR> | half is 16 so... quarter... eighth precision |
| 2026-04-27 18:02:38 +0000 | <davean> | NVFP4 if you're in AI |
| 2026-04-27 18:02:19 +0000 | <davean> | FP4 |
| 2026-04-27 18:02:18 +0000 | <monochrom> | toy example I would use in class to teach floating point :) |
| 2026-04-27 18:02:16 +0000 | <davean> | I did feed it both anyway, this is weird because I remember taking time to type that out ... but maybe I lost it in a quick reply to monochrom |
| 2026-04-27 18:01:59 +0000 | <EvanR> | what would you call a float with 4 total bits |
| 2026-04-27 18:01:47 +0000 | <davean> | EvanR: yes, 4 bits |
| 2026-04-27 18:01:36 +0000 | <davean> | I sure meant to type Int4/Word4 |
| 2026-04-27 18:01:35 +0000 | <monochrom> | Hey I haven't used Int4 for a while! Last time it was Casio FX-702P which was fabled to combine two 4-bit CPUs to do 8-bit work. |
| 2026-04-27 18:01:25 +0000 | <davean> | er didn't I? |
| 2026-04-27 18:01:21 +0000 | <EvanR> | four bits? |
| 2026-04-27 18:01:17 +0000 | <davean> | ijouw: I said I used both |
| 2026-04-27 18:01:03 +0000 | <haskellbridge> | <ijouw> Int4 or Word4? |
| 2026-04-27 18:00:42 +0000 | <davean> | I just consider int4 trivially small! |
| 2026-04-27 18:00:40 +0000 | <EvanR> | 10^80 cripples combinatorialists |
| 2026-04-27 18:00:34 +0000 | <davean> | I'm not against that. |
| 2026-04-27 18:00:29 +0000 | <davean> | I did test a searcg implimentation once by making it pametric and feeding it Int4 and testing all cases ... |
| 2026-04-27 18:00:12 +0000 | <haskellbridge> | <ijouw> Now I am trying to imagine an exclusive untrainfinitist |
| 2026-04-27 17:59:55 +0000 | <davean> | Yah, how many relations are there between particles in the universe? |
| 2026-04-27 17:59:32 +0000 | <monochrom> | I'm a cosmological finitist. I think that 10^80 ought to be enough for everyone. :) |
| 2026-04-27 17:58:59 +0000 | <davean> | I want more inclusive ultrafinitists |
| 2026-04-27 17:58:44 +0000 | <davean> | EvanR: Get me an ultrafinitist with a broader view then :) |
| 2026-04-27 17:58:29 +0000 | <EvanR> | 4 might be the largest possible number |
| 2026-04-27 17:58:09 +0000 | <EvanR> | an ultrafinitist might take exception calling X trivially small! |
| 2026-04-27 17:58:06 +0000 | <monochrom> | I missed that. Sorry! |
| 2026-04-27 17:57:40 +0000 | <davean> | Note the "trivially small" caviate :) |
| 2026-04-27 17:56:31 +0000 | <monochrom> | If you have "data X = C1 | C2 | C3; f :: X -> Int" then exhaustive testing is proof, there are only 3 cases to check. |
