OK. I will remove these nonstandard names first because I need to learn something before adding these nonstandard names.

Here is an off-topic question: Can you give me some suggestions for testing the nonstandard names? (I searched for tests for _copysign and _copysignf and tried to write tests like that, but it seems not good.) Thanks if you can give me some suggestions.
