The manual page documents standard IEEE 754 features, supported by our implementation. Alpha's FP_X_IOV should not be used; our architecture doesn't even maintain it properly since we call softfloat routines for conversions. We don't document it to discourage ever use it; we have plenty of precedents for those.
