IsAnInfinityOnlyRoundingMade​(AngouriMath.​Entity,​AngouriMath.​Entity)

Whether value is an infinity that only the decimals made. A sum, a product or a
power of exact finite numbers, the power's base not zero, is exact and finite, and is an infinity only
where the context's exponent range rounds it onto one: an exact power too large to build is the
decimal, and a complex product's parts are decimals, so 2^(10^10) and (3 + 4i)^2000 are
infinite as evaluated. An infinity counts as exact, and every expression holding one was simplified to
it. An operand that is a decimal already is not asked about: its power past the range is the
decimal's +oo, as it was. Asked only of a value that is not finite.
