Are all current math methods in the System library going to be updated with the new generic math support? I see in the documentation of several methods in the language's library the usage of various possibilities of numeric input parameters. Are those going to be updated to use the new INumber interface? I was just curious, because I imagine that would be a lot of work...

Most (all?) of the System.Math APIs are now directly available on applicable types. So you're expected to use those in a generic math context rather than System.Math.

For example, calling Sqrt generically looks like:

TNumber MySqrt<TNumber>(TNumber x)
    where TNumber : IRootFunctions<TNumber>
    => TNumber.Sqrt(x);

My understanding is that going forward System.Math/MathF will be considered legacyish and any new math operations will be added to numeric types directly. This goes for non-generic contexts too. (IE: double.Sqrt instead of Math.Sqrt)

Yep, this is correct.

Thanks for the answer! I'm already looking forward to the new generic math feature!

@AnteaterStudios have you been trying it? you don't need to wait for final release. there are up to date builds listed at https://github.com/dotnet/installer/

@danmoseley thanks, I will give it a try! Nevertheless, I'm still going to wait for the final release of .NET 7 to include it in my personal project.
