2021-02-19 14:49:44 +0200 | asked a question | A simple sum causes division by zero exception I'm very new to SageMath and did some small experiments yesterday. This is my Code: It works well if My ipynb file: nbviewer.jupyter.org/gist/7sDream/5db3cfd153269fd1a1cacaf0b60f69bb It seems some optimizations of sum did not consider the range of variable So how can I disable this sum optimizations? Or what is wrong with the way I use it? |
