What is the difference between const double and double const?

Question

I came across in a popular C++ blog the following code:

double const x = 1.0;

I know that const double* and double* const differ in a way that in the former the value is const while in the other the pointer is const. But what is the difference between double const and const double?

It's explained as part of [this](http://stackoverflow.com/questions/1143262/what-is-the-difference-between-const-int-const-int-const-int-const?rq=1) — chris, Sep 10 '13 at 16:35

double const x = 1.0 is identical to const double x = 1.0

Both are declaring a constant double-precision floating point variable.
