Thank you for your reply.

You are right sprintf(' %03.0f',1) should print "001" (not sprintf(' %3.0f',1)).
Do you agree it makes sense?

What I want to print is "  1". Do you know how this task can be accomplished?

About integers you are right again. But doesn't (although with warnings) C transform int to float when necessary?
