Hello,
What do you think Ans should return?
In CAS:
In Home:
Code:
3*4 12
isprime(Ans) 1
A bit disappointing, no?
What was the last thing you did on the CAS screen? I bet it was a prime number....
The problem is the CAS really can't be integrated like you want because there is severe incompatibility in many places with a "normal" calculator. Ans actually has 3 locations, cas screen, home, and RPN. They are all a bit different...
Yes I clearly understand that inside a CAS function Ans is the one of the CAS, and that the reason of this is the difficulty of integration between two universes.
But one can expect the CAS command, executed in the Home context, receives all the data of this context, Ans included.
In fact the syntax is important: it is not executed in the Home context, it is executed from the Home context.

Still, isprime is a CAS function so it uses Ans from the CAS environment. Where you executed it from is irrelevant to the calculator.
We do not like it either.... there just is not much that can be done unfortunately.

But this time a console opens

A strange frankenstein result, but does give both results
home Ans▶ console
Cas Ans▶ home
