Type Members

1. trait IsIntegral[A] extends IsReal[A]

   

2. trait IsReal[A] extends Order[A] with Signed[A]

   

   A simple type class for numeric types that are a subset of the reals.

3. trait IsRealFunctions extends AnyRef

   

4. trait NRoot[A] extends AnyRef

   

   This is a type class for types with n-roots.

   This is a type class for types with n-roots.

   For many types, the value returned by nroot and sqrt are only guaranteed to be approximate answers. Thus, many (most?) instances of NRoot will not be able to ensure that sqrt(x) * sqrt(x) = x.

   Also, generally nroots where n is even are not defined for negative numbers. The behaviour is undefined if this is attempted.

   It would be nice to ensure an exception is raised, but some types may defer computation and testing if a value is negative may not be ideal. So, do not count on ArithmeticExceptions to save you from bad arithmetic!

5. trait NRootFunctions extends AnyRef

   

6. sealed abstract class Sign extends AnyRef

   

   A simple ADT representing the Sign of an object.

7. trait Signed[A] extends Any

   

   A trait for things that have some notion of sign and the ability to ensure something has a non-negative sign.

8. trait SignedFunctions extends AnyRef
