xte::big_int::operator+()

`xte::big_int<T>::operator+()`

Defined in header <xte/math/big_int.hpp>

[[nodiscard]] constexpr auto&& operator+(this auto&&) noexcept;

Returns the object unchanged.

#1

[[nodiscard]] friend constexpr xte::big_int<T> operator+(xte::big_int<T> lhs, const xte::big_int<T>& rhs) noexcept(false);

Computes the sum of two big-integers. May throw if allocation fails.

#2

[[nodiscard]] friend constexpr xte::big_int<T> operator+(xte::big_int<T> lhs, xte::big_int<T>&& rhs) noexcept(false);

Computes the sum of two big-integers. lhs is destructively moved-from. May throw if allocation fails.

constexpr auto u64_max = 18446744073709551615ull;
static_assert((xte::big_int(u64_max) + u64_max).str() == "36893488147419103230");
