Hi
In Formula question type is it possible to use:
c = (a> b)? (ab): ((b> a)? (ba): 0);
How can use the conditional operator like
Sign = (a> 0)? ("+") : (a< 0)? ("-"): "");
to get a string variable?
Thanks

Well, I solved it on this wey:
Signos = ["+","-",""];
Posicion = (b > 0)? (0): ((b < 0)? (1): (2));
Signo = Signos[Posicion];
If you know better option, please tell me.
Signos = ["+","-",""];
Posicion = (b > 0)? (0): ((b < 0)? (1): (2));
Signo = Signos[Posicion];
If you know better option, please tell me.
Re: Conditional operator
this does work too:
s: if a>0 then "+" else if a<0 then "-" else "n/a"
s: if a>0 then "+" else if a<0 then "-" else "n/a"
Re: Conditional operator
Thanks, Teodoru.
No, that doesn't work.
No, that doesn't work.
I tried too:
s = if a>0 then "+" else if a<0 then "-" else "n/a"; with and without semicolon

Hi Miguel,
Sorry to hear that.
The question attached worked without errors on two different Moodle servers.
Is your question a stack type?
In Maxima, the assignment operator is ":" not "=".
Good luck,
Teo
Re: Conditional operator
The solution provided is for a STACK type of question, not for a Formulas type of question.
Sorry for misunderstanding.
