The default formatting is appropriate for music of a certain era and 
there are facilities to override the defaults.

There was a short discussion a while ago about packaging an alternative 
formatter with LilyPond, but it was all at this same level of confidence 
("I've seen", "I'm aware of") rather than citing specific examples.

My instinct is that a context property specifying the range of decimal 
places to print (at least N, no more than M) would serve the purpose, 
but it might be unnecessarily complicated.  Maybe it would be better 
just to provide an alternative formatter that prints the fractional part 
to its limit and leaves off trailing zeros.

It would be best to work from published examples.  For example, it would 
be nice to know whether Stockhausen ever specified a tempo with a 
trailing zero, e.g., 70.0.
