An equivalence for Doubles which is consistent with IEEE specifications.
An equivalence for Doubles which is consistent with IEEE specifications.
Because the behaviour of Doubles 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 numeric contexts.

An equivalence for Doubles which is reflexive (treats all NaNs
as equivalent), and treats -0.0 and 0.0 as not equivalent; it
behaves the same as java.lang.Double.compare.
