Prime calculator sum(1.0002^n/n, 1, 20000)

[Gil]

You are right, I forgot one zero.

A pity anyway to have to switch to HOME to get a simple result.

Observation
To be able to enter the beginning value for n (under the sigma-summation-sign) and the last summation value of n, I had to select TEXTBOOKS notation.

Is it possible to write it "normally" in ALGEBRAIC mode
(or in RPN like in the equation writer of the HP50G)?

Regards,
Gil
