non-incremental/QF_NIA/20230328-sqrtmodinv-hoenicke/sqrtStep7.smt2

This checks the validity of the newton-raphson step that computes
the square root from an initial approximation:

  assume abs(x - (res * res)) <= oldeps
  res = (res + (x / res)) / 2
  assert abs(x - (res * res)) <= neweps

where neweps depends on oldeps.  It also considers rounding errors
correctly.
