What can be done to programming languages to avoid floating point pitfalls?

The misunderstanding of floating point arithmetic and its short-comings is a major cause of surprise and confusion in programming (consider the number of questions on Stack Overflow pertaining to "numbers not adding correctly"). Considering many programmers have yet to understand its implications, it has the potential to introduce many subtle bugs (especially into financial software). What can programming languages do to avoid its pitfalls for those that are unfamiliar with the concepts, while still offering its speed when accuracy is not critical for those that do understand the concepts?
