Question 1210626
.

<H3>For a reader:</H3>

The difference / (the discrepancy) between the numbers 3.748996 and 3.748265
in the post by @josgarithmetic tells/indicates that the procedure used by @josgarithmetic in his post is ERRONEOUS.


In order to convince that a computational procedure is valid,
the discrepancy MUST be much lesser. 


I do not try to explain it to @josgarithmetic or to convince him (since it is useless).


I only want to aware a reader: do not accept wrong recommendations.
