this does break integers though

practical uses are boring
i love impractical math

I wonder what real life practice even exists for root square numbers?

#22736

If you’re doing Java, you can just cast it to an integer.

#22737

Oh, wait, I see what you’re doing.

#22738

You might laugh, but we used pythagoras principle, when we made the garage in our garden, so we will make sure it becomes a perfect rectangle. (Pythagoras uses square root, just for giving you an IRL example.)

Maybe then something like:

public int roundWrong(double number) {return -((int) -8.6);}
#22740

That’s still gives 9, doesn’t it?

#22741

I suppose! But besides geometry?

#22742

I think it rounds up to -8?

#22743

that breaks numbers like 8.3 tho

#22744

Let me check.

#22745

Right.

In story’s silly ahh goofball world of her own doing, collision detection. and like it probably isnt the best way for that either but I discovered theres absolutely nothing on this and now im just fascinated
you have the goober

goober.png(1)
goober.png(1)512×512 850 Bytes

she is currently fully in tile 10 or tile 3:2 of this image. tile 10 is blank. it doesnt do anything on interaction. all good. 3 rounds to 3 and 2 rounds to 2. a dummy function is called
but lets say you have a normal situation, where say, gravity is being applied. she goes down. just a teency bit.
she is now in 3.1:2. The tile being touched is 4:2. the previous tile that she is in more of doesn’t matter as the gravity of the game means she will never reach a tile faster than it can be detected.

Okay, now the goober moves left. On this tick, after gravity, she is at 3.1:1.9. the two functions that need called are 4:2 and 3:1

On any given tick only 2 tiles need to be interacted with, being near round x, far round y, and far round x, near round y.

is this overly complex?? yes! yes it is! i do not need to do this! there is no harm in using conditionals or my slightly clunky solution or taking an actual course on games development instead of just winging it like a boss! however. i think this is neat

I also think it’s neat.

#22748

Yeah, I think the solution is probably just to figure out the top number and subtract from that.
So like:

public int roundWrong(double number) {
   int upValue = ((int) number) + 1;
   return upValue - ((int) (number + 0.5));
}
#22749

The annoying part is that this is a piecewise function, so you’re not going to get any neat solution minus potentially some sin/cos wave shenangians?

#22750

my need to unneccesarily optimise random things will persist forever. I was born in the wrong generation man. Take me back to programming restraints and people making software on their own

meanwhile me writing python code and going ‘it works nya nya nya it doesn’t need to be fast it never runs with large inputs’

Question, @TodaysStory: if I have the number 8, in your thing, what would it round to?
