If you're manipulating bits in the float/double you will run into
problems. Most ARM systems have no hardware floating point, but there
exist several different softare emulations. They are not quite IEEE,
if memory serves, the mantissa is little-endian while the exponent part
is big, or something like that. You can't be sure since the FPE is a
pluggable module in the kernel - each one can use its own
representation.
