Bach.eval: Way to get the numerator and the denominator (like Numden in Mathlab)

[sydy]

Hy,
I'm looking for a way in bach.eval to find the numerator and denominator of a symbolic number.
Eg. I have the rational 4/5
I want to have as separate information the numerator n and the denominator d.
n =
4

d =
5

Thanks for your help.

M.

Well here's a dirty way I just found using regexp. Still would be happy about a more elegant solution.
