To use the shortest representation for the given precision unless
specified otherwise:

Ada 'Image attributes have "typographic quality" in plain contradiction
to the claim being for debugging purpose. That is why the plus sign is
always represented by a space and why floating-point representation is
always selected even for exact zero and the way the exponent part is
formatted. The typographic idea is to have *same looking* output. Note,
even if the output is mathematically incorrect as in the case of
floating-point numbers. 'Image considers precision and accuracy same,
which is *always* wrong when dealing with floating-point numbers.

It takes several parameters to control the behavior in a reasonable way.
