floating point format wrt endianness.

[Bill Allombert <allomber@math.u-bordeaux.fr>]

Hello, 

I would like to know the endianness of ia64 and also the way double are
stored wrt endianness. Is it the same as alpha ?

Specifically, in an union { double f; long i; } what are we getting in i?
in which way the ieee bitfield is packed ?

thanks for this information!

Bill.
