From code:

  # FIXME: Is it possible to convert real to some high-precision Python type?
  print "Warning: Converting real-valued parameter to double, might 
         looseprecision."

There are high-precision algebra libraries for Python. One called decimal, and 
is part of 2.4. However we need access to the c-api to write typemaps. I 
haven't found any documentation (yet) for this.

If anybody have other ideas for a solution please share!
