@brief return flattened JSON value @sa https://json.nlohmann.me/api/basic_json/flatten/

Computes floor(log10(pow(2, e))) for e in [-2620, 2620] using the method from https://fmt.dev/papers/Dragonbox.pdf#page=28, section 6.1.

A wrapper around fwrite that throws on error.

return whether the iterator is at end

@brief return whether value is an unsigned integer number @sa https://json.nlohmann.me/api/basic_json/is_number_unsigned/

! @brief determine system byte order @return true if and only if system's byte order is little endian @note from https://stackoverflow.com/a/1001328

Computes lhs * rhs / pow(2, 64) rounded to nearest with half-up tie breaking.
