Hi 1) From the only example I found s = PowerSeriesRing(QQ,'s').gen() a=exp(s);a.pade(4, 0) type(a)
it seems this works for type 'sage.rings.power_series_poly.PowerSeries_poly'
But I have a type 'sage.symbolic.expression.Expression' b, and was unable to convert b to the type required to apply pade
2) There's an alternative rational.reconstruct , but that seems to be geared to computations modulo (n) 3) In conclusion, it seems at current stage the simplest is to write one's own Pade? Thanks, Florin
