- NaN and Infinity are not part of the C Standard.
- They're part of the IEEE floating point standard (IEEE Std 754-1985).
- The exact relationship between IEEE floating point and Standard C
- is still being discussed, but in the meantime your best bet is to
- read the IEEE floating point standard. Unlike the C Standard,
- it's short and easy to follow.
