me.  Query.
Should the continued fraction expansion be added for all
reasonable irrational constants in oeis?
I haven't thought through this.
thoroughly enough though (cough).

my Euclidean algorithm (1987) [Beeblet BBC Acorn..NZ/
a code for hashing your pin number.. myprog SeriCalc4S]
calculates continued fraction  terms (denominators) and
the list of Convergents for any
computer machine-number. Hence efficient or interesting
or preferred convergents may be selected.  below.

Unfortunately,
I do not how to *list continued fraction convergents with Pari gp.
