I'm ask to think of an solution for an Webapp that does some math
on data in an database.
The problem is, the DB has about 40.000.000 entries, the webapp
needs to do mainly math on that data, the math should be
"traceable", so no wild round offs.
The explanation is too generic to guess whether Perl is suitable or
not. It depends for instance on "the math", how intensive are the
calculations, how often they need to be done, etc. Depending on the
details pure Perl can be just fine, or Perl + Stored Procedures, or
Perl + C, Perl + Math::Pari, Perl + PDL, .... Can you be more
specific please?
Just in case it helps Math::FixedPrecission can take care of
precission in floating-point arithmetic if you need that kind of
control. There are modules to deal with integers of arbitrary size or
fractions. Maybe you could search for "Math::" in search.cpan.org and
see what's there.
