Comment(by jdemeyer):
Replying to [comment:28 cremona]:
> However, I have adjusted the test for being integral (i.e. for z to b in
the period lattice) in a way that I hope is a reasonable compromise:
namely that the coordinates w.r.t. the lattice basis should be
approximately integral in the sense that their fractional part is at most
{{{2^(0.8*prec)}}}.
I like this solution. The {{{elliptic_exponential()}}} code looks fine to
me. However, I would like somebody else to review the heegner stuff.
One small suggestion: the doctest for {{{elliptic_exponential()}}} is
quite long, so I would separate it in an {{{EXAMPLES}}} part and a
{{{TESTS}}} part.
