(12C Platinum) Internal Precision Test

[Gamo]

This well know program shown that 1/n! can be used to verify the series
e = 1/0! + 1/1! +1/2! + ... + 1/n! to approximates the value of e .

Each iteration compare this to the 12C Platinum's value of e .

-----------------------------------------

Procedure:

[R/S] display each iterations from this formula Pause and display calculator's e
When both are equal then display the total iterations.
[X<>Y] to view the value of e

-----------------------------------------

12C Platinum took 14 iteration which mean that the internal precision is more than the Original 12C where 12C took 11 iterations.
