Status: New Owner: asmeurer Labels: Type-Enhancement Priority-Medium New issue 1455 by asmeurer: Split expand so that it only expands a*(x+y) => a*x+a*y http://code.google.com/p/sympy/issues/detail?id=1455
It would be nice if expand was able to only expand by distributing multiplication, and not doing things like pulling powers out of logs. This in particular would help my implementation of combine for combining logarithms so I can turn (a+b*I)*log(x) into a*log(x)+b*I*log(x), which can then become (if x>0) log(x**a)+b*I*log(x), but not make log(x**2) => 2*log(x), because this is not true without the right assumptions (x>0). -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
