[plt-scheme] C-style Printf Format Convention?

In fact format returns the result as a string. To write it to the 
standard output you should use (printf format-string arguments) instead.

Anyway I don't think this solves the problem of choosing accurately the 
right number of digits of a floating point number as you can do in C.
