Classes
class	mysql::math::Kahan_sum< Value_tp >
	Tracks the state of the Kahan summation algorithm, which produces a sum over a sequence of floating point numbers with very low numeric error, using an internal error compensation term. More...

Namespaces
namespace	mysql
namespace	mysql::math

Functions
template<class Value_t = double, std::input_iterator Iterator_t>
Value_t	mysql::math::kahan_sum (const Iterator_t &first, const std::sentinel_for< Iterator_t > auto &last, Value_t init=0)
	Compute the sum of values in the given range, with very low numeric error. More...
template<class Result_t = long double, std::input_iterator Iterator1_t, std::input_iterator Iterator2_t> requires std::is_arithmetic_v<Result_t> && std::unsigned_integral<decltype(*std::declval<Iterator1_t>())> && std::unsigned_integral<decltype(*std::declval<Iterator2_t>())>
Result_t	mysql::math::sequence_sum_difference (const Iterator1_t &begin1, const std::sentinel_for< Iterator1_t > auto &end1, const Iterator2_t &begin2, const std::sentinel_for< Iterator2_t > auto &end2, uint64_t init=0)
	Compute the sum of values in the first sequence, minus the sum of values in the second sequence. More...
