Documentation
class Unital r => DecidableAssociates r where Source
Methods
isAssociate :: r -> r -> Bool Source
b is an associate of a if there exists a unit u such that b = a*u
This relationship is symmetric because if u is a unit, u^-1 exists and is a unit, so
b*u^-1 = a*u*u^-1 = a
Instances
isAssociateIntegral :: (Eq n, Num n) => n -> n -> Bool Source
isAssociateWhole :: Eq n => n -> n -> Bool Source
