"testxxxxname", what did you expect? You are using numerical math and therefore should be prepared for numerical round off errors.
See attached that the error is just in the range of 10^-14 % - pretty good, I think.
See also two different ways to deal with the "problem", while the most obvious would be to cancel beforehand (I let Mathcads symbolics do the work) or apply some scaling.
