Why I do not obtain the correct result? ArcTan[x,x^2]/.x->-0.00001 gives 3.14158 But, Limit[ArcTan[x,x^2],x->0,Direction->-1] gives 0 The same happens with the directional limits of the Sign[x] function. One obtains 1 (!?) even if Direction is -1. The enhanced version of Limit (Calclulus,limit package) does not change these results.
