Category: Lisp Core  Simplification Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Stavros Macrakis (macrakis) Assigned to: Nobody/Anonymous (nobody) Summary: simpsum/simplify_sum with summand=f(i)+q Initial Comment: sum(q,i,1,inf) => asks whether q is pnz and gives inf,0,minf This is correct, and works with simpsum:true, simpsum:false, and simplify_sum. Similarly, sum(f(i),i,1,inf) always returns a nounform. However, sum(f(i)+q,i,1,inf),simpsum => inf (without asking whether q is pnz) Same thing with simplify_sum.
