Comment #5 on issue 1696 by asmeu...@gmail.com: integral of heaviside http://code.google.com/p/sympy/issues/detail?id=1696
I bisected the fix to commit 65f483e40306f186537e8d9eb0fff3029b40ac61 Author: Chris Smith <smi...@gmail.com> Date: Sun Nov 13 09:59:04 2011 +0545 evalf: 1->1.0; no expand or conjugate with symbolic expressions Expanding a Mul or Power makes sense when dealing with numeric expressions, e.g. (1 + I)**2, but need not be done for symbolic expressions. The same applies for the use of conjugate to deal with expressions like 1/(1 + I). Also, +/-1 were not being processed but they are now. The only caveat is that the negative 1 on an expression like -x is not changed to 1.0. -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
