log_to_int is only available for Givaro fields because it represents finite field elements as their logarithms internally, e.g. a^10 is stored as 10 internally. > Also, if there is a conversion from polynomials to integers, it would > have sense to have a backward conversion from integers to polynomials. > It can be done similarly as sage: K.<a> = GF(3^10) sage: K.fetch_int(10) a^2 + 1 I don't claim the name is fitting or anything :) Cheers, Martin -- name: Martin Albrecht _pgp: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 _otr: 47F43D1A 5D68C36F 468BAEBA 640E8856 D7951CCF _www: http://www.informatik.uni-bremen.de/~malb _jab: [email protected] -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org To unsubscribe from this group, send email to sage-devel+unsubscribegooglegroups.com or reply to this email with the words "REMOVE ME" as the subject.
