Apologies if this is double-sent; I thought I sent it already but
don't find the submission.
Suppose I have a discrete function, as at the bottom (in this case a
frequency distribution).
Does anyone have a good example for producing a bar graph? Ideally I
would like both latex
and some graphical
For integers, Pari also has an ispower function. I think that
it is useful to have an n.is_power(k) member function
for integers (or more general for ring elements which admit
unique factorization of polynomials), and prefer the syntax
n.root(k) rather than n.nth_root(k)
