Re: HP Prime: What's wrong with this program? Message #2 Posted by cyrille de Brébisson on 15 Oct 2013, 2:07 a.m., in response to message #1 by BruceTTT
Hello,
At the root cause of the problem is the fact that the CAS does not have access to your local variables. Basicaly, we did everything we could to have the CAS and the numeric world as integrated as possible, however, local variable is something that we did not manage to do 100%
Yours is a case where that fact pops up to the surface...
Here is how you could do what you want:
in CAS, do:
Solver(a,b,c):=BEGIN solve(a*x*x+b+x+c=0,x); END;
This will create a CAS progam (which can be called from numerical)...
