(is_decimal_floating_point_v<T> && ...)

when fold expressions are available, and

std::conjunction_v<is_decimal_floating_point<T>>

I did not know conjunction existed. Learn something new everyday. Thanks.
when not.

(Or mp11::mp_all instead of std::conjunction.)

But that's not what the common_type constraint said. common_type<int,

decimal32> is decimal32, so it would accept (int, decimal32). (But would

not accept int by itself, or (int, int).)
