BigNum++

Lightweight, high-performance C++ port of https://github.com/Patashu/break_infinity.js

Relies heavily on constexpr optimizations.

BigNums are represented internally as $\text{m} \times 10^\text{e}$, using double m and uintmax_t e.

Note: e is unsigned. This means that BigNums can only store numbers as small as regular doubles, but the upper limit is higher.

Maximum representable value is std::nextafter(10.0, 0.0) × 10^numeric_limits<uintmax_t>::max(), effectively 1e($2^{64}$).
