Oh, sure. But those applications should also not use the floating point equality operators. They deal with opaque data, and should make sure not to corrupt it.

Keep in mind that the ISO standard does require that floating point equality tests return false for values that have the exact same binary representation, and that not everything adheres to it and some environments may give you false for identical values even when the standard says it should be true. Also, != is not the negation of == for floating point. So even using those operators to test a round trip over those applications is iffy.
