Thanks Mr. Artur Lipowski  for your response.
Is the fact that avr-library stores floats and doubles in 4-bytes, documented 
in any of its manuals or guides. I mean how are we programmers to know that 
without digging into its code.

>Why you nedd to "manually" load float into registers?
I want to display the decibel value ( in double )
for that I will have to take it our through the 8 bit ports. 
Thats why I wanted to load the float/ double in the registers.
If there is a more elegant solution please let me know.
