|  |  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outdated, use / instead
