D.8.6.8 invertNumberMain
Procedure from libraryzeroset.lib (see zeroset_lib).
- Usage:
- invertNumberMain(f); where f is a polynomial
- Purpose:
- compute 1/f if f is a number in Q(a), i.e., f is represented by a
polynomial in Q[a].
- Return:
- poly 1/f
- Assume:
- basering = Q[x_1,...,x_n,a], ideal mpoly must be defined and != 0 !
- Note:
- outdated, use / instead
