1: if it is safe to combine 2 (or more) ternary conditions.
as in this way : (e>f) ? “e” : (f<g) ? “f” : “g” - with : e=2, f=4, g=8
or if that is not recomended.
Don’t see anything wrong with that, if that’s the most readable way to present your code go for it.
Ok, so when I’m trying to change the last condition >/<…it always returns me with “g” (never “f”)…
So, how would one writte it so that it also returns f when f<g is true…
testing in jupyter localhost
Sorry I’m not sure I’m following you - the last condition is
(f < g) in your post above, and when you change that to
(f > g) and you have
f = 4,
g = 8 then that’s false and hence
"g" is returned. What output are you expecting?
Ooops, my bad, the f value was changed = to 8 (f=g)
so that is why (I guess) it was always returning me “g” in both case (f>g) or (f<g)…wich is somehow interesting to know too…
you do not receive an “error/warning” msg if both values are equal, meanwhile you check if one is greater than the other ! it just returns you the last value of the condition I guess…
answer : (e>f) ? e : (f<g) ? “f” : “g” (…and f=4)
f is returned now. which is what I was expecting
I guess that is why they mostly advise us to use “>=” instead of strict “>” !
Why would you expect an error or warning if both values are equal? Doing e.g.
4 < 4 is perfectly legal and unambiguously false. Use
== to explicitly handle cases where numbers are equal.
it does sounds logical to me that 4>4 could possibly return a warning…
as for using > instead o >=… as of now, i’m just following this online course : Conditionals | JuliaAcademy
thanks for your time nils ! I guess that is solved by now
I think you’ll struggle to find any programming language where
< give a warning for equal numbers - it is a pretty unambiguous question (“is number one bigger/smaller than number 2”) with an unambiguous answer. Similarly, you wouldn’t expect
1 < 2 to return something like “it’s still smaller, but pretty close!”
In any case it’s always helpful to consider the documentation, here’s the relevant section: Mathematical Operations and Elementary Functions · The Julia Language
