Is there any context where it makes sense to have fractional pixels? Like millipixels, micropixels, nanopixels, etc.? There is of course sub-pixel text rendering; does anyone refer to numerical fractional pixels in that field (333.33 mpx)

Well, to be fair, many/most programs aren't using complex numbers, or concerned with inexact vs. exact numbers, significant digits, or really even scientific notation.

Looks like fweimer is correct for scheme. I admit to being very surprised. Here is the verbiage from various rXrs: r3rs, r4rs & r5rs (section 4.2.6): https://standards.scheme.org/official/r3rs.pdf https:/&#

How do you get that to work? #lang racket (read-syntax-accept-graph #t) (let ((a '#0=(0 . #0#))) (display (car a))) ...which of course doesn't work, because `(read-syntax-accept-graph)` is a run-time thing, and the

Is Prolog bicameral? Because it has a `read` predicate? Is bicameral then just a matter of implementing a `read` function which returns a tree of tokens, which you could implement for C or Python? Which makes bicamerality a property of a

It looks like Racket nerfed the shared-structure / "Datum Labels" for circular lists and the like (I see it is still in section 2.4 of r7rs): '#0=(0 . #0#) ...and I should have included `#|block comments|#`, datum

The pedantic point of the article is that an error in this situation isn't correct. The average is 8e307 and 8e307 is 8e307.

Chapter 4 of "The Art of Prolog" ("The Computation Model of Logic Programs") is about that very topic. It doesn't go into gory details on how to optimize an interpreter for fast execution, but it does go into enoug

A good book to read to get aquainted with these notions is "Meta Math" by Gregory Chaitin. The impatient can jump to chapter 5. https://arxiv.org/abs/math/0404335

Seconded. I've only just started it, but it really resonates with me so far. It is about how to better use time / avoid distraction.
