@isuruf Sympy has S.Infinity**S.Zero == 1 while wolframalpha give NaN Which should we follow in SymEngine?
Also that error I was getting before got resolved when I changed Infinity class to Infinit everywhere…. I think Infinity is overlapping with something C++ already has… I tried to fix it but couldn’t. Need some help on it.

NaN. It is an indeterminate form

Yes I know
Actually the answer depends on how we think about it… if we think in terms of x->0 then oo^x is NaN but if we think of x as exact zero then oo^x is zero… I think thats where SymPy and Wolframalpha differ… I was asking which one should we follow in SymEngine(as in which thought process among the two)
