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.

Cosine Implementation in C
https://github.com/JuliaMath/Bessels.jl/blob/master/src/bess...
Thanks! I love it, so easy to understand and follow.
My favourite work on the subject is Fredrik Johansson's:

Whenever I feel down and without energy I just read something in there

A Modern Fortran Scientific Programming Ecosystem
Most of the old Fortran code isn't that great. To the extent it's optimized, it's optimized for PDP era hardware where memory was fast, floating point was slow, fma didn't exist, vectorization didn't exist, computers weren't fast enough to do tedious symbolic math to find better routines, and they weren't fast enough to test hundreds of millions of inputs to ensure correctness and accuracy. The datastructures, algorithms and tuning and testing were never great, and are worse on modern computers. For a simple example of how much of a difference this can make, look at https://github.com/JuliaMath/Bessels.jl which is often 10x faster than AMOS (the old reliable Fortran code).

Cosine Implementation in C
well OK, but figure this one out:
https://github.com/ifduyue/musl/blob/master/src/ctype/casema...
How do you regenerate it when the Unicode version changes?
-
What are some good C programs I can read through?
musl-libc
- How to create fundamental libraries for my language?
- Regex and gcc versions
- Implementing Cosine in C from Scratch
-
How do I find the actual code of C functions?
https://git.musl-libc.org/cgit/musl (musl, another open source implementation, I've heard this one has more readable code)
