GaussianIntegers
GaussianIntegers
is an option for FactorInteger, PrimeQ, Factor, and related functions that specifies whether factorization should be done over Gaussian integers.
Details
- With GaussianIntegers->False, factorization is done over the ordinary ring of integers
. - With GaussianIntegers->True, factorization is done over the ring of integers with i adjoined
. - The Gaussian primes used when GaussianIntegers->True are chosen to have both real and imaginary parts positive.
- The first entry in the list given by FactorInteger with GaussianIntegers->True may be
or -I.
