Translated to SMT-Lib by Maple SMTLIB package.

Application: CAD calls of In[20] on page 13 in
M. Kauers, SumCracker: A Package for Manipulating Symbolic Sums and Related Objects, 
Journal of Symbolic Computation 41(9), 2006, pp. 1039-1057. 
(https://www.sciencedirect.com/science/article/pii/S0747717106000502)

All denominators in the original CAD call got cleared by introducing disjunctions with sign conditions:
a/b == c/d --> a d==b c && b<>0 && d<>0
a/b >= c  --> a >=b c && b >0  or ( a <= b c && b < 0)
