Why make such a choice to use a return 1.0 / 0.0;

What compiler are you using and what message does it output?

@codeplea It get information:

divide or mod by zero

Please copy/paste your command-line compiler invocation and what it says.

To fix your issue, you can merely change the line to return NAN;.

I propose INFINITY instead. That is also a C99 macro. It works with Microsoft Visual Studio C++ 2022 in a C project

Why prefer INFINITY over NAN?

Because 1/0 seems to say +infinity. I think it would be reasonable to say that 0/0 is not-a-number.
