interestingly enough I have a blog post about this
… but it is not ready yet (the blog post)
> plot doesn’t really do anything with the data before plotting it, not always true — for example, the function renderer will sample the input function at discrete positions, and for a more “extreme” example, see the density renderer…
Sorry I missed this. I would have much rather been in your meeting than the other one I was in.
Next meet up Sat, 1 May 2021 at 20:00 UTC https://gather.town/app/wH1EDG3McffLjrs0/racket-users
Awesome :slightly_smiling_face:
Very niche question about Racket CS—it seems real->floating-point-bytes allow 32-bit floats even though they’re not generally available in Racket CS. Can we rely on this going forward? We use it in Herbie…
Which reals are you providing as inputs?
Yes, that function will work to write 4-byte values even if there are no number values that are represented as 32-bit floats — that is, you can rely on it being available in CS
:+1: Thank you @mflatt. And yes @samth we are providing double-precision flonum values that happen to be exactly representable as single-precision flonum values.
There’s some timeout stuff in the sandbox module, IIRC

any idea how I can use ASCII nul in a regular expression? I’m trying to use regexp-match to get a sequence of characters, none of which is "<" (less than) or the null character. In https://docs.racket-lang.org/reference/regexp.html ASCII nul does indeed show up, but it looks like it needs to be at the end of a pattern. Based on what I see in the docs about nul, I’ve tried #px"[^<\\]" but this doesn’t work (square brackets aren’t balanced)
ah, nevermind, I figured it out: I can write (regexp-match #px"[^<\u0000]+" s) (matching a string s) and it works
