Question

What is the result of the following operation defined by IEEE754?
\[ \text{(NaN == NaN)} \]

• A. false
• B. true
• C. error
• D. 1

Hint:

In IEEE754, NaN is not equal to itself, which is why the expression \( \text{NaN == NaN} \) returns false.

Answer 1

The Correct Option is A

In IEEE754, **NaN** (Not a Number) is a special floating-point value used to represent undefined or unrepresentable values. According to the IEEE754 standard, **NaN** is not equal to itself, which means the expression \( \text{NaN == NaN} \) evaluates to **false**. This is designed to handle undefined operations, like division by zero or square root of negative numbers. 
Conclusion. 
Thus, the result of the operation \( \text{(NaN == NaN)} \) is **false**.
