Integer Ring [HB 40]

New features:

• An experimental implementation of the number field sieve (NFS) is now available.
• The Cunningham database of factorizations of the form $a^n \pm 1$ due to Brent and te Riele has been updated to the latest version (April 11, 2001).
• The function KroneckerSymbol(x, y) now works for y = 0, and matches the definition given in Cohen for y < 0.

• Many of the basic functions for orders of number fields have been extended to include the ring of integers.

Bug fixes:

• Raising $-\infty$ to the power of $-\infty$ now returns 0 instead of an error.
