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
<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.
The above is the detailed content of How to Check if Your C Compiler Follows the IEEE 754 Floating-Point Standard?. For more information, please follow other related articles on the PHP Chinese website!
