Seems to me insisting that the number after the dot be
called "precision" in all cases is imposing a foolish
consistency.

There's a third thing that %-formats use it for as well:
for a string it means the maximum number of characters
to include.

To my way of thinking, the format string just lets you
specify uop to two numbers, the interpratation or wnich
is up to toe format concerned.
