this will make number like 34 for instance
use 4 spaces ^^^^34 before it for formatting.
( think of the ^^^^ as 4 spaces)

In this case you have 6 digits and two of them
are right of the decimal point. eg 1.7 would be
written as ^^^1.70.

This is true, but when you use -Wall -Wstrict-prototypes
-Wmissing-prototypes, you will get at least a warning if not an
error. You should turn on as many warnings as possible,
because people make mistakes and this way the compiler
can find them for you.
