==Multiplication and division==
Could someone post examples of correct multiplication and division of power series, and perhaps even an explanation of the correct algorithm? The Haskell code is invalid, and I just wrote a translation of the D/Java code, which gives wrong results: multiplying 2 by 1 yields 3 + 3x + 3x^2 + ... --[[User:Kevin Reid|Kevin Reid]] 00:04, 17 February 2009 (UTC)
: I hope multiplication of the Ada solution is correct. As for division, it is impossible to implement because the result can infinite (example: 1-''x'') or non-existent (example: ''x''). --[[User:Dmitry-kazakov|Dmitry-kazakov]] 15:14, 10 March 2009 (UTC)
