What mathematical primitives could be further supported

[chrishobcroft]

This is quite a general question, cognicent that there are libraries in Solidity emerging for things like complex arithmetic amongst other things.

The topic is: what other mathematical primitives could be further supported in Solidity.

One idea: geometric arithmetic, e.g. scalar / vector products.

Thanks for starting this discussion, @chrishobcroft. General topics are welcome!

Here are the mathematical primitives that I think would be useful for DeFi:

• Linear Algebra (what you suggested)
• Complex numbers
• Trigonometry (Matt Solomon has a library for this: solidity-trigonometry)

FWIW, I am toying with the idea of adding support for complex numbers in PRBMath by adding two new value types, C59x18 and U60x18.
