BigInt support?

needs more discussion. cc @ljharb

I think it would be a great potential change to make (only needed before stage 2.7) to allow 2-3 BigInts, instead of only 2-3 Numbers.

[Richienb]

Should the change be made here, or in a separate proposal along with Math.min and Math.max?

Also Decimal128 (stage 1) ?

At least some of the Math methods (e.g. sumPrecise) cannot be made to work with BigInts, so none of them should.

[ljharb]

If that was a reasonable consequence of that proposal advancing, then that should have been discussed prior to it reaching stage 3, as part of the “cross-cutting concerns” requirement. I don’t see any reason that it’s all or nothing for Math BigInt support.

[bakkot]

I mentioned several times that sumPrecise did not support BigInt inputs. That this implies other Math methods should not support BigInt inputs is my opinion only (which I've also stated several times, such as in the thread linked above).
