RE: (12C Platinum) Internal Precision Test
(12-31-2018 10:33 AM)Gamo Wrote: 12C Platinum took 14 iteration which mean that the internal precision is more than the Original 12C where 12C took 11 iterations. 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. |
