Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

C library for multiple-precision floating-point arithmetic with correct rounding
At the risk of just talking to myself, I'll note that a google scholar search on the [1] above led me to this phd [2] which in turn led me to two newer tools, Verrou [3] and Verificarlo [4] which involve Valgrind and Docker, respectively, though I'd have to understand what exactly is being contained by Docker for Verrou. But it makes me appreciate more the minimalist approach of Knizia et al. in [1], which does involve recompilation of modified assembly, but that's something I'm doing multiple times with student code already.

Is there a language which can keep track of the potential epsilon error when doing calculations?
I don't know why everyone else is talking about bignums, but this is a fairly common subject of interest with lots of research projects out there. Off the top of my head Arpra, and CADNA. Julia also has IntervalArithmetic.jl which can be used with some manual work. None of these are core language features, but I don't imagine that was an important part of the question.
What are some alternatives?
When comparing verificarlo and arpra you can also consider the following projects:
sleef - SIMD Library for Evaluating Elementary Functions, vectorized libm and DFT
tiny-bignum-c - Small portable multiple-precision unsigned integer arithmetic in C
verrou - floating-point errors checker
ama - A system to amalgamate any features you want into any language you need
vpu-count - Information about AVX-512 support on recent Intel processors
