Thank you very much for replying. 1--If I understood you correctly, apache commons will keep only the existing 5 math-related libraries. Meaning that any math theory has to be implemented in 1 of these 5 libraries. Is that correct? 2--my implementation uses only BigDecimal for unlimited precision. No primitives are involved. Of course I can change that, but the point of OrionMath was to have unlimited precision. 3--of course I would be willing to do the work of implementing the thing the Apache Way. 4--there is functionality that already exists in the commons math-related libraries. Absolutely. I would implement math algorithms that don't exist. 5--I built that library, because I wanted to apply the math stuff i learnt in the math school from 2004-2008. I wanted to start a library in late 2008, but I only got around in doing it in 2019+2020. 6--i built it only to get happiness from it and not because I needed a math library. But i am sure that AI, physics, data science and all branches of engineering would need a comprehensive math library. I understand the YAGNI principle, but I don't know how many people have to implement their own math library that do the things OrionMath does, because the open source libraries don't provide those algorithms.Take vector algebra, for example. How many functions do math libraries have related to vectors? Mine has 60 functions just for vectors. There are useful stuff there that are needed in machine learning or physics. You know? 7--here is my code https://github.com/orionlibs/orion/tree/main/orion_math/src/main/java/com/orion/math
