the bug is not in Maxima, but the problem is in the fact that sage has keepfloat set to true. look at this:
(maxima called from sage wit your expr:1.4*(.1873*z+.1752)/(z-1)/(z-. 8187) ) maxima: keepfloat:false false maxima: partfrac(expr,z) 1851969/(661600*(z-1))-1914101474313/(82700000*(9123*z-7469)) Robert.
