Symbol join of \ll and equal

Symbol join of \ll and equal

[Xan]

Hi,

I just want to know if there is a symbol that join \ll and = like \leq 
joins < and =. If not, it's possible to "make" that symbol (that has << 
in upper and - in bottom; like \leq but with two <<)?

Thanks in advance,
Xan.

PS: In The not so short introduction to latex there is no such symbol. 
Maybe in ConTeXt....

No doubt you _could_ define such a symbol, but what is the meaning of
it?  The statement “a ≪ b” means a is _much_ less than b; i.e., not
anywhere near b, let alone _equal_ to b.

B.T.W., I don’t see this in the Comprehensive LᴬTᴇX Symbol List, but
there is Unicode character U+2AA3 [⪣] “Double Nested Less-Than with
Underbar”.

Joel, Thanks a lot.
I searched a symbol for "f \symbol g iff for large x f(x) < g(x)". 
What's the most adequate symbol here?

Thanks,
Please, CCme.
