Map an iterator of pairs into a pair of common numeric types

Accept an iterator of pairs of numeric (or numeric-coercible) values and returns an iterator of pairs of numerics coerced to the least greater common type, assuming a hierarchy of representations.

Arguments

• i - An iterator over pairs of numeric (or numeric-coercible) values
