Question regarding [c.math¶11]

In C++11, [c.math¶11] says:

> if any argument corresponding to a double parameter has type double or an integer type, then all arguments corresponding to double parameters are effectively cast to double.

(The latest draft appears to contain equivalent wording.)

About `isnan` in particular, cppreference¹ says:

> bool isnan( IntegralType arg ); (since C++11)

...which appears to be a result of the above quoted paragraph.

Accordingly, is this snippet expected to compile?

   long long x = ...;

At least MSVC rejects it². Is my understanding wrong, or is MSVC
