Then it isn't a C compiler and/or library.

Do you really mean "long float"?  In K&R that's a synonym for "double"; ANSI
removed this and added "long double" for which the format is "%Lf" (note
uppercase L).  The elegant solution would've been "short float" (formerly
"float"), format "%hf"; "float" (formerly double), format "%f"; and "long
float" (what ANSI calls "long double"), format "%lf", but elegance must defer
to compatibility.  Sigh.
