Re: [sage-support] Re: [sage-cell] Where Oh Where is my Divide By Zero Error?

Hi, It is not related to exponentiation; it is due to the difference between symbolic evaluation and real-valued evaluation when dividing by zero. Real-valued arithmetic mirrors the IEEE floating point standard, I expect: sage: 1.0/0 +infinity While symbolic evaluation gives the divide-by-zero
