Unit Tests: Fixed compile error in Divide test with newer Apple Clang

[JanosGit]

I ran into a compile error here when attempting to build the unit tests with a recent Xcode version. Seems like the compiler attempted to instantiate the function template with some invalid types. The lambdas with explicit argument types fixed it.

That's really strange. Aren't other arithmetic tests done in the same way?

Another question: Are the unit test failures on Linux related or for another time?

[JanosGit]

From what I get this is caused by some explicitly overloaded operator/ definitions from the Xcode 15 standard library. Unfortunately, the change which fixes the macOS build now explicitly breaks the Linux build.
