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.

How to calculate large factorial number in C ?
Large? Factorials get very large very quickly. Do you need pointers to a bignum library? https://github.com/kokke/tiny-bignum-c

Library for arithmetic operations on integers represented by arrays
tiny-bignum-c looks what you want.... the code is also very small and hackable

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?
nim-stint - Stack-based arbitrary-precision integers - Fast and portable with natural syntax for resource-restricted devices.
ama - A system to amalgamate any features you want into any language you need
LibTomMath - LibTomMath is a free open source portable number theoretic multiple-precision integer library written entirely in C.
arb - Arb has been merged into FLINT -- use https://github.com/flintlib/flint/ instead
break_infinity.js - A replacement for decimal.js for incremental games who want to deal with very large numbers (bigger in magnitude than 1e308, up to as much as 1e(9e15) ) and want to prioritize speed over accuracy.
gmp-wasm - Fork of the GNU Multiple Precision Arithmetic Library (GMP), suitable for compilation into WebAssembly.
gmp-extensions - Extending GNU MP library.
calc - C-style arbitrary precision calculator
