scala.math.Equiv.Double.StrictEquiv
See theStrictEquiv companion object
trait StrictEquiv extends Equiv[Double]
An equivalence for Double
s which is reflexive (treats all NaN
s as equivalent), and treats -0.0
and 0.0
as not equivalent; it behaves the same as java.lang.Double.compare.
Because the behaviour of Double
s specified by IEEE is not consistent with behaviors required of an equivalence relation for NaN
(it is not reflexive), there are two equivalences defined for Double
: StrictEquiv
, which is reflexive, and IeeeEquiv
, which is consistent with IEEE spec and floating point operations defined in scala.math.
This equivalence may be preferable for collections.
