To be more precise, NaN is never equal to _anyth
Adam D. Ruppe:
nan never equals nan,
Additionally, the init NaN doesn't have the same bitpattern as
the other. There are many NaNs.

nan never equals nan, this is in the floating point spec used by
D, C and others.
Use this instead:
http://dlang.org/phobos/std_math.html#isNaN
I seem to be having some difficulty with the nan and init
properties of floating point types. Can anyone explain why the
following assertions all fail:
assert(float.init == float.nan);
assert(float.nan == float.nan);
assert(float.init == float.init);
Thanks.
