Re: Comments on the suggestion to use infinite precision math for wide int.

yes but the relevant question for the not officially static integer
constants is "in what precision are those operations to be performed

expect the math to be done within that type, i.e. exactly the way you
expect the machine to perform.

As I explained in an earlier message, *within* a single expression, we
are free to use higher precision, and we provide modes that allow this
up to and including the usea of infinite precision. That applies not
just to constant expressions but to all expressions.
