Jonas,

Not really sure, but you might look at:

"atom_to_float64()"

Syntax: include machine.e
s = atom_to_float64(a1)

Description: Convert a Euphoria atom to a sequence of 8 single-byte values.
These 8 bytes contain the representation of an IEEE floating-point number in
64-bit format.
Comments: All Euphoria atoms have values which can be represented as 64-bit
IEEE floating-point numbers, so you can convert any atom to 64-bit format
without losing any precision.
Integer values will also be converted to 64-bit floating-point format.

Example:
 fn = open("numbers.dat", "wb")
puts(fn, atom_to_float64(157.82)) -- write 8 bytes to a file
