EuclideanDomain

catdef.spad line 413 [edit on github]

A constructive euclidean domain, i.e. one can divide producing a quotient and a remainder where the remainder is either zero or is smaller (euclideanSize) than the divisor. Conditional attributes: multiplicativeValuation Size(a*b)=Size(a)*Size(b) additiveValuation Size(a*b)=Size(a)+Size(b)

divide: (%, %) -> Record(quotient: %, remainder: %)

divide(x, y) divides x by y producing a record containing a quotient and remainder, where the remainder is smaller (see sizeLess?) than the divisor y.

euclideanSize: % -> NonNegativeInteger

euclideanSize(x) returns the euclidean size of the element x. Error: if x is zero.

extendedEuclidean: (%, %) -> Record(coef1: %, coef2: %, generator: %)

extendedEuclidean(x, y) returns a record rec where rec.coef1*x+rec.coef2*y = rec.generator and rec.generator is a gcd of x and y. The gcd is unique only up to associates if canonicalUnitNormal is not asserted. principalIdeal provides a version of this operation which accepts an arbitrary length list of arguments.

extendedEuclidean: (%, %, %) -> Union(Record(coef1: %, coef2: %), failed)

extendedEuclidean(x, y, z) either returns a record rec where rec.coef1*x+rec.coef2*y=z or returns “failed” if z cannot be expressed as a linear combination of x and y.

multiEuclidean: (List %, %) -> Union(List %, failed)

multiEuclidean([f1, ..., fn], z) returns a list of coefficients [a1, ..., an] such that `` z / prod fi = sum aj/fj``. If no such list of coefficients exists, “failed” is returned.

sizeLess?: (%, %) -> Boolean

sizeLess?(x, y) tests whether x is strictly smaller than y with respect to the euclideanSize. Note: zero is considered smaller than every nonzero element.
