rnd(-1) (or any negative number) seems to yield a random number from -32768 to 32767.
also rnd() seems to yield a random number between 0 and 1
not sure if those are intended features, but they surely aren't documented.
I think rnd() -> (-32768,32767) and maybe rnd(x) -> sgn(x)*rnd(abs(x)) would make more sense.
edit: plus srand() doing something to the effect of srand(time()) would be nicer than defaulting to srand(0)
32768 is the max value of an int in pico, so that's interesting maybe that trick will come in handy some day. Also, if you're looking for better documentation: https://neko250.github.io/pico8-api/
@scottyelish:
ouch!
@orangecode:
yes, that's a full 32 random bits (16 integer part + 16 mantissa) and that's definitely useful. having that on rnd() (no parameter) and rnd(x) returning a number between 0 and x (or x and 0) would be slick.
yes, I know that doc, it's nicer but not much more thorough. (at this point, maybe there's a full book that needs to be written?)
ultra ... I was doing something that ended up like rnd(10-level) ... which worked great until level 11 :-)
anyway, take a look ... let me know what you think:
The wiki intends to be more thorough than the official docs. Specifically, the API reference is intended to be a place where we can accrue detailed info on each function.
@scottyelish: had a look and commented there :)
@dddaaannn: I have a silly problem with the wiki: I just can't read that red on grey...
I can try to tweak the colors more. The original goal was to pick from the Pico-8 palette, and the current pick is the least offensive choice in that regard. I've seen it look worse on some monitors than others for reasons I don't understand.

hey, that salmon/peach color looks a whole lot better, thanks! bookmarked :)
the red text here on the bbs is also hard to read but far less prominent (few people bother with a title in their post). the current top banner is painful though (red glyphs on grey)
