Of course, but I was thinking of floating point numbers in particular
at the time of writing where the image depends on S'Digits. As base
subtypes of float have a 'Digits attribute depending on 'Machine_Radix
and 'Model_Mantissa there is clearly some implementation dependence
here.
I have found that, in general, 'Image is ideal for printing out
information for trace and debug purposes, but you really need to use
the xxx_IO facilities to get fine control over your output
representation.
