I need a power regression function and I need it to be accurate, look what happens

> X := Vector([1, 2, 3, 4, 5, 6], datatype = float);

> Y := Vector([1, 4, 9, 16, 25, 36], datatype = float);
> PowerFit(X, Y, x);

                                            (1.9999999999999998)
      (1.0000000000000004) x                          
> f(x):=1.*x^2.;( using CTRL+L to get the result)

                                         1.9999999999999998
x -> 1.0000000000000004 x                 
How can it get this result ?
