Concrete methods

final def defaultFromBigInt[@specialized(Int, Long, Float, Double) A](n: BigInt)(implicit ev: R[A]): A
final def defaultFromDouble[A](a: Double)(implicit ringA: Ring[A], mgA: MultiplicativeGroup[A]): A

Returns the given Double, understood as a rational number, in the provided (division) ring.

Returns the given Double, understood as a rational number, in the provided (division) ring.

This is implemented in terms of basic ops. However, this is probably significantly less efficient than can be done with a specific type. So, it is recommended to specialize this general method.
