Forgive me if I've got what you need wrong, but can't you use the euphoria
atom_to_float, float_to_atom functions to get the ieee format you require?

eg

atom your_double_value

atom a_double_value
a_double_value = allocate(8) -- allocate 8 bytes to hold your floating point

your_double_value = 1.23564

-- now poke 8 consecutive memory locations with the ieee representation
-- of the value in your atom
poke(a_double_value,    atom_to_float64(your_double_value)

(hope the above is correct!!)
I would think that once you have your floating point atom poked into
memory you should be able to use your assembly code to get at it.

All the best
