Really?  A Google search for "q 11.5 notation" brought this up as the sixth hit:

http://en.wikipedia.org/wiki/Q_%28number_format%29

That will tell you just about everything you need to know.

PS - Thanks for making me look it up - I never knew what  q number format was!

Thanks for the reply ..

What i understood :

 To convert float number to Q11.5 notation,

in this case m=11 and n=5.

According to this if my float value is 10.1235 then i need to multiply 10.1235 with 32(2^n=2^5) so the value will be 324.

is it right process ?

kindly clarify me

Appears to be right, but don't forget to round to the nearest integer.
