[Question] Numeric integer and decimal constraints

[Ultrahead]

There are open issues requesting a way to restrict generic types that are numbers, but is it also considered to indicate whether that numeric parameter is integer? For example to achieve something like the following pseudo-code:

public static TNumeric GetWrappedValue<TNumeric, TInteger>(this TNumeric arg0, TInteger arg1)
   where TNumeric: struct, "numeric"
   where TInteger: struct, "integer"
{
   return arg0 % arg1;
}

... beaing arg1 of type byte, int, long ...

See #110 and #1711 . I don't think we'd have language-built-in constraints for these particular things, but you could use those features to achieve that if you wanted to.

[Ultrahead]

I see. Thanks.

@Ultrahead does that solve the issue? Would you like to close it?

[Ultrahead]

@amis92 that depends on the final implementation of such features when available.

[Ultrahead]

Now that C# 9 is coming next, will it include a feature that allows to achieve something as shown in my initial post?

Or ...

public static TNumeric Add(this TNumeric arg0, TNumeric arg1)
where TNumeric: struct, operator+
{
return arg0 + arg1;
}

No, neither shapes nor numeric constraints will be part of C# 9

[Ultrahead]

Well, let's hope they make it for C# 10, then.
