gp: x^(1/2) and (1/x)^(1/2) and sqrt(x) |
Pari-dev, ? (1/x)^(1/2) *** log is not analytic at 0. ? x^(1/2) *** not an integer exponent for non invertible series in gpow. ? sqrt(x) *** odd exponent in gsqrt It seems to me that this is a confusing variety of error messages. Perhaps there might be a way to make them more comparable? It is further interesting that : ? (1/x^2)^(1/2) *** log is not analytic at 0. ? (x^2)^(1/2) *** not an integer exponent for non invertible series in gpow. ? sqrt(x^2) %3 = x + O(x^15) Perhaps it would be easy to make these comparable also? Shalom, Michael
