Generic Math in .NET 7
summary
Generic Math in .NET 7 introduces a concrete claim and a working toolset: dozens of new numeric interfaces applied to primitives that let one write a single generic algorithm instead of many overloads. It adds 30+ interfaces and static abstract interface members, new operator forms like create checked and checked/unchecked operator overloads, and new types such as n128 and Half. Library refactors (LINQ average/sum) remove duplicated code — removed ~830 lines — and runtime work keeps startup fast.
