You are a stupid programmer, you can't have that

Floating-point, if anything, is *more* complex and comes with more
pitfalls than signed/unsigned mistakes. Worse yet, it *appears* to
behave like what most people imagine real numbers to behave, but in fact
doesn't, which makes mistakes more likely, and also harder to catch
because they usually only crop up in special corner cases while
generally appearing to work correctly.

At the end of the day, it boils down to: you have to learn how your
programming language and its types work. If you imagine you can just
cowboy your way through programming without fully understanding what
you're doing, you only have yourself to blame when the results are
disappointing.
