Well. Go back and investigate the rules for floating point notation
('Dezimalpunktschreibweise' in german)
_ _
in math and you will see, that anything like 0.19 or 9.9 is
illegal. These numbers are (per definition) equal to 0.2 or 10.

A rather complicated way to show the obivous :-) What he wanted to say
_
is: 3 * 1/3 = 1. (1/3 = 0.3)
