xte::big_int::big

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

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

Definitions

template<xte::is_arithmetic T = U>
[[nodiscard]] explicit(!xte::is_int<U>)
constexpr big_int(U x = 0) noexcept(false);

Constructs from an integer or finite floating-point value.

#1

[[nodiscard]] explicit(false) constexpr big_int(const xte::big_int<T>&) noexcept(false) = default;

[[nodiscard]] explicit(false) constexpr big_int(xte::big_int<T>&&) noexcept = default;

The moved-from big-integer is left in an unspecified state.

#3

template<typename U>
requires(!xte::is_same<T, U>)
[[nodiscard]] explicit constexpr big_int(const xte::big_int<U>& other) noexcept(false);

Constructs from another big-integer which stores chunks of a different type.

#4

template<typename Range = xte::array<T>>
[[nodiscard]] constexpr big_int(std::from_range_t, Range&& range, bool neg = false) XTE_ARROW_CTOR(/* ... */)

Copies qualifiers from Range onto its element type. Requires that T is constructible from the element type of the given range.

#5

template<xte::is_int Radix = xte::uz>
[[nodiscard]] explicit constexpr big_int(xte::string_view string, Radix radix = 10, const xte::number_format_config& config = {}) noexcept(false);

Constructs from a string representation of an integer.

Example

static_assert(xte::big_int("FF", 16) == 255);
