I do have to disagree here as it is entirely possible, in the world of hardware interfacing, that an external hardware device could possibly supply an sNaN
Indeed. But since there's no guarantee in Python that this sNAN will make it through to the Python code, I'm not going to make any guarantees about what happens. The problem is that at least one OS (Linux) may, under some circumstances, convert sNANs to qNANs, and that affects Python. So unless that changes, the behaviour of float sNANs is platform dependent. -- Steven
