Does python suck or I am just stupid?

Floating point math does work. It just doesn't work the way
some people expect it to. Unfortunately, there's no way to
make computer arithmetic work exactly the way everyone expects,
because not everyone expects the same thing. It might be
possible to make it work roughly the way most people expect,
e.g. by doing exact rational arithmetic and displaying
rationals whose denominators are of the form 2**m*5**n
in decimal notation, but that approach opens up problems
of its own with efficiency. (Because a single arithmetic
operation can take an unboundedly long time, and a single
number can take up an unboundedly large amount of memory,
and it's hard to predict in advance whether that's going
to happen to you.)
