This is one of the most primitive aspects of all formatting
used so far - it very often uses far more digits than are significant,
which makes the printouts confusing to read
(Can you ever put tables straight into reports, papers and books? - I think
Occasionally, far worse, too few digits make output positively misleading.
Since there is a generation of std::C++_programmers who have never seen a
statement before, I think the preoccuation with the format string,
showing its inheritence from FORTRAN and BASIC,
is rather backward looking (though I can see that some people want it).

Longer term I think this is where we should be encouraging efforts.
(I have been exploring ways of printing only the right number of significant
but this is not yet anywhere near ready for the furnace of Boosters
