Most of the time I want the same number of decimal places.  I think 
being able to provide a default decimal place would be a good idea.

Perhaps it could be in the first part of the string.  Then it could just 
append it (to hide from design/localizers/myself) something like: 
"%.2f()" ~ "blar: %(value)". Or maybe "%.2f=default" ~ "blar: %(value)".

Agreed.
