Algebra.ToInteger

The two classes C and C exist to allow convenient conversions, primarily between the built-in types. They should satisfy

  fromInteger .  toInteger === id
   toRational .  toInteger === toRational

Conversions must be lossless, that is, they do not round in any way. For rounding see Algebra.RealRing.

I think that the RealIntegral superclass is too restrictive. Non-negative numbers are not a ring, but can be easily converted to Integers.

A prefix function of (Algebra.Ring.^) with a parameter order that fits the needs of partial application and function composition. It has generalised exponent.

A prefix function of (Algebra.Field.^-). It has a generalised exponent.
