nice addition. I see GET_STR_DC_THRESHOLD is in [8, 22], whereas
SET_STR_DC_THRESHOLD is in [141,4351]. I would expect both thresholds
to have the same order of magnitude. Even SET_STR_DC_THRESHOLD should
be smaller since fast input relies on multiplication, whereas fast
output relies on division.
GET_STR count in limbs, SET_STR count in base-10 digits (and the SET_STR
threshold are then somewhat suboptimally applied for any base input).
PS: a minor point: some thresholds are not sorted by increasing value,
for example http://gmplib.org/devel/MUL_TOOM44_THRESHOLD.html
Thanks, I have sorted that out now. :-)
