The only thing unusual about IEEE values on ARM is that the word
ordering of doubles is opposite to that on x86. I suspect that it's
this you're running into. Many compilers have special cases for this.
Otherwise, to the best of my experience (apart from some minor quirks of
which x86 also has its fair share) ARM behaves totally as expected for
IEEE operations.
