final class FPFilter[A] extends AnyRef

A Floating Point Filter [1] provides a Numeric type that wraps another Numeric type, but defers its computation, instead providing a floating point (Double) approximation.
trait FPFilterWrapper[A] extends AnyRef

A typeclass approach to wrapping numeric types in an FPFilter.
final class MaybeDouble extends AnyRef

A MaybeDouble will hold a Double approximation so long as the Double's sign can be computed exactly.
