Numerically compare values

I was wondering whether there is a way to numerically compare values. I don't want to use == due to the limited precision of floating point arithmetic. There are some possible solutions, for example here:

My question is, is something like this already implemented in sage?

Your question is quite too vague: What are the values you are trying to compare? How were they defined? In Sage, there are a lot of solutions for numerical values: multiple-precision floating-point arithmetic (using mpfr), interval arithmetic, ball arithmetic, exact representation for algebraic numbers, etc.

@bmoi: please give an example of your use case, this will help others give relevant answers.
