Thank you for taking the time to review my patch and for pointing out the issue with the ULONG_MAX test case. I failed to think about how a 32-bit system would treat ULONG_MAX == 4294967295.
To address this, I was thinking of updating the test case to use a large enough value that remains within the bounds of unsigned long for both 32-bit and 64-bit architectures instead. Specifically, 2147483648 (2^31), which has an integer square root of 46340. I believe this would ensure the test remains valid and portable across all supported architectures.
The updated test case would be as follows:
{ 2147483648, 46340, "large input"}
I'd appreciate any feedback on this proposed change and thanks again for your time Nicolas.
