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.
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.
