Yes. Notice that also this code:

struct A
{
  static const int a = 45;
};

is invalid without a matching definition. That is, you need to provide a single 
definition of:

const int A::a;

which obviously cannot be put in a header file. If you wonder why you need a 
definition, consider what happens if some user code does "&A::a", which is of 
course legal. Or think that to load a floating point constant into the CPU we 
need to fetch it from memory (which address if you don't provide a definition?)

In fact, I personally use this to expose constants without linkage:

struct A {
   enum { a = 45 };
};

but with floating point numbers you are out of luck.
