IIRC, 12C internal precision digits are rounded-away after each operation.
Only 10 sig. digits remains (what you see is what you get).

If the same applied to 12C Platinum, why did it need more terms to reach 10 digits of e ?
I would guess it would need about the same iterations:

2
2.5
2.666666667
2.708333334
2.716666667

2.718055556
2.718253969
2.718278771
2.718281527
2.718281803

2.718281828

BTW, getting it converge to 10-digits of e is just lucky. Last digit might be off due to rounding error.
Example, next iteration of above is 2.71828183

If the goal is to test internal precision of calculator, this test is not very good.
