hello there, i am really fresh on c#(and new here too), and i cant understand how to use these! (i checked the documentation a ton of times)
i actualy understand what they are for, but cant apply. 
…
i have a float variable that needs to be 0 at some point, but since its an acceleration variable, when the script finishes subtracting, its never Zero, witch is inderstandable, but i cant have a model still moving after a command! thanks in advance!
With Mathf.Approximately you can check if your variable could be 0 without the float imprecision.
If that is true, then do something or dont do something.
Maybe stop substracting and set it to 0.
I cant tell you how to apply this if i dont how you setup your code.
Maybe there is even a better solution to that.
it is said that the mathf.approximately is dictated by how much you set Epsilon… how would i do that?
I think the documentation here is pretty clear: Unity - Scripting API: Mathf.Epsilon
However, let’s break this down.
In computer science, the Greek letter epsilon (which looks like ε) is often used to represent “a tiny amount,” or “the smallest amount that matters.”
[It can also be used to represent a set of things that are of interest in a search, but that doesn’t apply here.]
When you have to compare various amounts in floating point numbers, a common way to do that is to say “is it close enough?”
If your mom told you to get a couple dozen eggs, and you came back with 25, that would be close enough if your epsilon was 1. (24 ± 1 includes 25)
In Unity, if you set Mathf.Epsilon to be 1, that means that you’re okay with calling 24 ± 1 good enough. If you set Mathf.Epsilon to be 0.0001, then your tolerance for unequal numbers is 1/10000. 24.0001 or 23.9999 is close enough, but 24.0002 or 23.9998 is not acceptable.
thanks, but as i said, i did understand how it works, but what ai dont know, is the exact placement of the syntax on the code… recently i did used it, and i set the script to return the epsilon value, and it did return “1,4”… very interesting, but can i actually set the Threshold of the epsilon? i mean, a value that ranges from … lets say, 0.01 to 0.01 for instance?
sorry for my slow line of thought hehehe
