   Does this actually allow for any optimizations?  As @andrzej-kaczmarek said, floats are always promoted to doubles anyway, so I am skeptical that this actually does anything (but then what do I know?  I am not a compiler...).
   
   If this is a useful change, then it should be conditional on a syscfg setting.  `%f` is defined as the double format specifier in the C spec, so that should be the default behavior.
