Remarks
- The IEEE standard for floating point value encoding has specific values for:
- Infinite - the result of a division by 0 (zero).
- Not a number - the result of 0 / 0.
- The DIV operations are interpreted and never result in a division by 0 (zero).
- An invalid value may come through an IO driver or protocol.
