Comment #27 on issue 2039 by julien.rioux: Mul.eval_subs problems http://code.google.com/p/sympy/issues/detail?id=2039
Got another one for you In [1]: from sympy import * In [2]: a,b,c=symbols('abc') In [3]: (-I*a*b).subs(a*b,c) Out[3]: I*c Should have been -I*c. The bug is in master as well. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group. To post to this group, send email to sympy-iss...@googlegroups.com.
