Headline: says something. (That is obviously not true and just clickbaiting)
Instant disclaimer: the headline is not good, it should be instead “don’t do this other thing”.
Later in the article: how do we avoid doing the thing I told you not to do? By doing what I told you not to do.
The dude may be correct (idk, haven’t bothered reading the rest of the article), but he doesn’t know how to write/communicate. I don’t believe he’s respecting my time. Just tell in the title what you actually want to talk about.
I got a LITTLE bit further than you.
Boils down to “make the ‘close enough’ number have some real meaning in your domain instead of just picking an arbitrarily small one”
… at least to my read. Again, like you, didn’t finish.
Say, you have a turn-based game where units move on a grid. … Then you realize that the move finishes exactly when the position of the unit coincides with the target cell’s center.
I mean, something like
inbetween(target - cellRadius, target + cellRadius), no?And of course you first (and generally) convert the floating points to units you can actually work with, why is this even a question? Anyone who knew KSP as more than a rocket explosion simulator, learned that lession long ago from the Kraken.
That’s one case study. He lists many more where throwing an epsilon at a floating point problem is the wrong solution.
