non-incremental/QF_NIA/20230328-sqrtmodinv-hoenicke/sqrtStepFinal.smt2
This checks the validity of the final newton-raphson step that computes
the square root from a good approximation
assume abs(x - (res * res)) <= oldeps
roundedDown = x / res
res = min(res, roundedDown)
assert res * res <= x < (res + 1) * (res + 1)
