TBA

  • Add Field typeclass, instances, and functions.
  • Add Euclidean and GcdDomain instances for (), CDouble, CFloat, and Complex.
  • Add Ring and Bits instances for WrappedFractional and WrappedIntegral.
  • Add fromInteger and fromIntegral functions for Ring.

0.4.2: [2019.06.06]

  • Remove unlawful instances of Ring (thanks to @Bodigrim for noticing these)
  • Add fromNatural to Semiring typeclass (thanks @Bodigrim)
