Hi Samuel,
How are in the proposed extension the resulting very large numbers represented?
In other words, how are the limitations of double precision overcome and can we
do math with such very large integers?
PS: In Scilab the gammaln() function allows computing the logarithm of the
factorial for large integers.
Hello Rafael,
Please see the link to the help page posted in my first message. It is
documented in the page.
The algorithm can be seen on CodeReview (ref in the message/bugzilla
entry). It uses a careful
processing with log(). It is more accurate than gammaln() by a factor of
up to 100 (it is also
documented in the test).
Regards
Samuel
