double x=45.9876 ;
printf("%4.2f" , x); is working fine ... But printf("%*f , 4.2 , x) ;
behaves odd in my fedora 8 pentium machine. any clue ?
Does * substitute only integers ?

I don't know when you want to use such calls, how should I? And what
has the linux kernel to do with this, this doesn't came up before, and
what is '*our* practical use'?

If you want to control the format dynamically.
scanf("%d" , &first);
scanf("%d" , %second);
printf("%*.*f", first ,second , x);
