Hi All, The following is a bug. Isn't it?
sage: f=sqrt(pi)^-1*exp(-x^2/2); f e^(-1/2*x^2)/sqrt(pi) sage: g=integral(f,(x,0,2)); g 1/2*sqrt(2)*erf(sqrt(2)) sage: n(g) Traceback (most recent call last): ... TypeError: cannot evaluate symbolic expression numerically sage: h=1/2*sqrt(2)*erf(sqrt(2)) sage: n(h) 0.674933236039321 Apparently, there is no difference between g and h. Perhaps internal representations are different...
