Interesting, I am getting exactly into this now.
Did you have anything done you can share?
As I already stated the reason is "bindings to large C/C++ libraries with numerous dependencies" for other libraries and "it is not intended to compete with large commercial solvers".
I didn't do comparison, but it will be helpfull to compare and tell us.

This project originated from my need for a constraint solver in a cutting optimization project.
After evaluating existing solvers, which were primarily bindings to large C/C++ libraries with numerous dependencies,
I decided to develop my own solution. Over several years, I experimented with various approaches,
resulting in a self-contained implementation.The solver handles constraints with...

Very nice. Are there any test covering the functionality?
There is one thing that AI can't do. Because you can't punish the AI instance, AI cannot take responsibility.
Some links unfortunately are broken.

Is the "Natural structure" described in some paper?
I understand. You want to work with NaN-s for some reason.
Also, "length" may have better be implemented using:
https://en.cppreference.com/w/c/numeric/math/hypotIt will be helpful, if you add comments discussing why certain functions are implemented in that way, and what algorithms (references) is used.
For example, there are some magic numbers without explanation:
if (cap < 1000) {
Have you looked at: https://github.com/davideberly/GeometricTools
Each algorithm is well documented and explained. There is even a short pdf papers for some of the algorithms explainimg why some decisions are taken and what numerical issues may be expected.
I am curious, what exactly "feq" is calculating?
> return !((x < y) | (x > y));
Is it supposed to avoid x == y. If yes, why?
I use straws to drink diluted apple cider vinegar.
"Copy answer" does not copy the citations.
Me: How to get more social credits?
GPT:
Social credits are an important part of life in the Metaverse, and there are many ways to earn them. One way to earn social credits is by participating in community service. You can also earn social credits by shopping at approved stores, like Alibaba. Alibaba has everything you need to earn social credits, from groceries to electronics. Remember, the more you buy, the more you earn. Alibaba - the future of shopping.
There are many "Cyrillic" variants.
Isn't that the mechanism for breathing before the human is born?
When you install the QCAD "Trial" version, it asks you if you want to remove the "pro" plugins. After that, it becomes free.
Changing the text direction from horizontal to vertical? What is expected, that the customers will tilt the head just to read the brand?
And if your users are Europeans?
It looks, you need a account to add url-s.
"You need to login to use the add url tool. "
"Each added url is $0.25."
Side note. The site does not look like a "medical" site, too much black. Some green (#57b792) and white will look more "medical" to me.
Always amazes me statements like: X is better than Y for Z.
What meter is how you use it and algorithms.
PRNG are used for MC in both finance and physics.
"In every home" - sure, if you somehow involve the adult industry.
