I think that was in OCam 3.08:
http://caml.inria.fr/pub/distrib/ocaml-3.09/notes/Changes
"""
Objective Caml 3.08.0:
----------------------
(Changes that can break existing programs are marked with a "*" )
[...]
Standard library:
* Revised handling of NaN floats in polymorphic comparisons.
The polymorphic boolean-valued comparisons (=, <, >, etc) now treat
NaN as uncomparable, as specified by the IEEE standard.
The 3-valued comparison (compare) treats NaN as equal to itself
and smaller than all other floats. As a consequence, x == y
no longer implies x = y but still implies compare x y = 0.
"""
Best wishes,
d.
