Cannot define user defined literals

Question

I was reading about user-defined literals, and I came across this snippet, but I got compiler error when I tried to use it.

int operator ""_fix(long double d)
{
     // returns d as a 1.15.16 fixed point number
     return (int)(d*65536.0f);
}

It says Error : Expected an operator. I am on Visual STudio 2013, which I believe has good support for C++ 11. Any ideas what is going wrong?

VS 14 CTP [does support](http://blogs.msdn.com/b/vcblog/archive/2014/06/11/c-11-14-feature-tables-for-visual-studio-14-ctp1.aspx) it, if you're brave enough to install it. — Praetorian, Jul 17 '14 at 23:25
@Praetorian Is there any info about when the stable release for VS 14 is coming out? — The Vivandiere, Jul 17 '14 at 23:26
I think I remember reading last quarter of this year, but I'm not sure. — Praetorian, Jul 17 '14 at 23:31

Remember that there must be a space after "" and before the suffix. So you should write:

int operator "" _fix(long double d)
{ // ...

This is not true, and doesn't answer the question. – Jonathan Wakely Mar 16 '16 at 10:29
