How to Check if Your C Compiler Follows the IEEE 754 Floating-Point Standard?

Does Your C Compiler Adhere to IEEE 754 Floating-Point Standard?

Unlike C, C provides a more straightforward approach to verifying whether your compiler conforms to the IEEE 754 floating-point standard. This verification is crucial for ensuring consistent behavior in numerical computations.

Within the C standard, the class resides within std. To access its static members, simply utilize the following syntax:

<code class="cpp">std::numeric_limits<double>::is_iec559</code>

<code class="cpp">std::numeric_limits<float>::is_iec559</code>

These expressions evaluate to true if the compiler employs IEEE 754, and false otherwise. Alternatively, the second part of Adam's response in the original question can also be applied to C to achieve the same functionality.
