Your question is far too ambiguous. You should make available an explicit example of a polynomial and a k that are want to try to do this with. For example, this problem is completely different depending o whether the coefficients of the polynomial are floating point or say huge exact rational numbers, or maybe numbers in an algebraic number field... > > - That all the roots of this polynomial are real > > - That the largest root is below $k$. > > What is the fastest way to check this? > > -- > You received this message because you are subscribed to the Google Groups > "sage-support" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To post to this group, send email to [email protected]. > Visit this group at http://groups.google.com/group/sage-support. > For more options, visit https://groups.google.com/d/optout. -- William (http://wstein.org) -- You received this message because you are subscribed to the Google Groups "sage-support" group.
