Uncertainty in measurements.

[Fedexcito]

I recently purchased an HP Prime, a very good calculator, I really like it, but after reading its manual, I could not find anywhere that uncertainty could be used in this calculator.

As an engineering student, I would really appreciate that the calculator contains that possibility to work with uncertainty in the measurements.

I would greatly appreciate if someone could answer me if this is so, or that I did not see it in the manual.

Thank you!
