Why does Perl say 10.2 is 10.19999999999
Because it is. Within the limits of precision of your floating point format, you're talking about the same number. This isn't just Perl; every programming language has _something_ like this. Some hide it more than others, of course. But no computer can do arithmetic with "real" numbers just like a mathematician does. So we use floating point as an approximation. In some cases, it causes unexpected results, as you found. If you need more precision, Perl has extended precision math modules available on CPAN. This doesn't solve the problem, of course; but it can hide it well enough for most purposes.
