OrderOfUnbuiltPowers​(AngouriMath.​Entity,​AngouriMath.​Entity)

The sign of left - right where either side is an exact power too large to build and the other is a
real number or another such power, decided without building either: two powers of one positive base by
their exponents, exactly, and otherwise by the signs and then by the logarithms of the magnitudes, where
those differ by more than the error of computing them. null where nothing decides it,
which leaves the comparison written; in particular, two magnitudes that may be equal are never told
apart. As the decimals, these powers were +oo and 0, and 2^(10^9) > 2^(10^9 - 1) was False. https://github.com/asc-community/AngouriMath/issues/1448
