.net - What does >+ and >- mean in C#

I had accidentally tried this, which compiles! So I was wondering what could this possibly mean.. google didnt help..

if (3 >+ 4)
   dothis() //this is never hit btw..

if (3 >- 4)
   dothis() //this is hit.

Both the code compile btw..

It parses as

3 > +4

and

3 > -4

So into the unary + and unary - operators.

If you want an interesting way to explore this, write

Expression<Func<int, int, bool>> func = (x, y) => x >+ y;

and then explore the resulting expression tree func in the debugger. You'll see the unary operator in the tree.
