Dear Robert,
Thanks a lot for the quick answer. This should work. However, I think it
would be nice to have a pre-parser that converts all sorts of number
formats into python ones so that mixing different packages for
different tasks would be easier. But I suppose this should be discussed
in another thread (?).
Cheers
Stan
