An equivalence for Floats 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.Float.compare.
An equivalence for Floats 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.Float.compare.
Because the behaviour of Floats 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 Float: 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.
