Type Members

  1. class BigDecimal extends ScalaNumber with ScalaNumericConversions

  2. class BigInt extends ScalaNumber with ScalaNumericConversions

  3. trait Equiv[T] extends AnyRef

    A trait for representing equivalence relations

  4. trait Fractional[T] extends Numeric[T]

  5. trait Integral[T] extends Numeric[T]

  6. trait LowPriorityOrderingImplicits extends AnyRef

    This would conflict with all the nice implicit Orderings available, but thanks to the magic of prioritized implicits via subclassing we can make Ordered[A] => Ordering[A] only turn up if nothing else works

  7. trait Numeric[T] extends Ordering[T]

  8. trait Ordered[A] extends Comparable[A]

    A trait for totally ordered data

  9. trait Ordering[T] extends Comparator[T] with PartialOrdering[T]

    A trait for representing total orderings

  10. trait PartialOrdering[T] extends Equiv[T]

    A trait for representing partial orderings

  11. trait PartiallyOrdered[+A] extends AnyRef

    A class for partially ordered data

  12. trait ScalaNumericConversions extends ScalaNumber

    Conversions which present a consistent conversion interface across all the numeric types
