This is something I've needed quite frequently, but I've never been bothered enough to code it myself. I usually just use Mathematica (EconomizedRationalApproximation or MiniMaxApproximation). It would be great to have in sympy or mpmath. Fredrik -- You received this message because you are subscribed to the Google Groups "sympy" group.
