question concerning Ans
Hello,
I have an issue with "Ans": Example: nextprime(1000000) ENTER returns 1000003 (which might be correct, I don't know for sure) but when entering now nextprime(Ans) ENTER I get 2 as a result. Entering directly nextprime(1000003) ENTER I get 1000033, which seems plausible. What is going on there? Are there some restrictions with Ans? Thomas

Since nextprime() is a CAS function it picks up the Ans from CAS, which is the result of some calculations you have done there earlier. More information about this behaviour is in this link Hope this helps Cheers, Terje

RE: question concerning Ans
Thanks, Terje!
I repeated my calculation within CAS  the problem was gone! So what I learned by this: do all CASCalculations in CAS. Thomas

RE: question concerning Ans
Hello,
yes, as a general rule, do all CAS calculations in CAS and all numerical calculations in home. We have invested a considerable amount of work in trying to make Home/Cas interactions as seamless as possible to allow home/cas cohabitation, but in some cases, like this one, it does come back to bite us.
