Support BigInt?

[Fil]

t === 1 ? B : A + BigInt(Math.round(t * Number(B - A))) seems to be working

see also #73.

I don’t think we can support BigInt yet—it’s still missing from Safari on both desktop and iOS.

Also, it’s a little pointless to interpolate BigInts since you’re necessarily losing the arbitrary precision that BigInt gives you by converting to floats. If you want to interpolate BigInts, it probably makes more sense to convert to a Float64Array (or number) first.

Yes. Exception is when you want the exact values at t=0 and t=1. Anyway it was a nice exercise :)

We should fix the exact values at t={0,1} per #73 independent of the type.
