Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
template<typename T>
|
|
inline SPROUT_CONSTEXPR T const&
|
|
min(T const& a, T const& b);
|
|
|
|
template<typename T, typename Compare>
|
|
inline SPROUT_CONSTEXPR T const&
|
|
min(T const& a, T const& b, Compare comp);
|
|
|
|
Requires
|
|
========================================
|
|
|
|
| Type T is LessThanComparable.
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| The smaller value.
|
|
|
|
Remarks
|
|
========================================
|
|
|
|
| Returns the first argument when the arguments are equivalent.
|
|
|
|
Examples
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
#include <sprout/algorithm/min.hpp>
|
|
#include <sprout/array.hpp>
|
|
using namespace sprout;
|
|
|
|
SPROUT_STATIC_CONSTEXPR auto input = array<int, 10>{{-1, 1}};
|
|
SPROUT_STATIC_CONSTEXPR auto result = sprout::min(input[0], input[1]);
|
|
static_assert(result == -1, "min value is -1.");

Interface
|
|
========================================
|
|
.. sourcecode:: c++
|
|
|
|
template<typename T, typename Compare>
|
|
inline SPROUT_CONSTEXPR T
|
|
min(std::initializer_list<T> t, Compare comp);
|
|
|
|
template<typename T>
|
|
inline SPROUT_CONSTEXPR T
|
|
min(std::initializer_list<T> t);
|
|
|
|
Requires
|
|
========================================
|
|
|
|
| T is LessThanComparable and CopyConstructible and ``t.size() > 0``.
|
|
|
|
Returns
|
|
========================================
|
|
|
|
| The smallest value in the initializer_list.
|
|
|
|
Remarks
|
|
========================================
|
|
|
|
| Returns a copy of the leftmost argument when several arguments are equivalent to the smallest.
|
|
| If an implementation not support C++14 initializer_list (``SPROUT_NO_CXX14_INITIALIZER_LIST`` defined), then this function is not specified constexpr.
|
|
|
|
Complexity
|
|
========================================
|
|
|
|
| Recursive function invocations in *O(logN)* (logarithmic) depth.
|
|
|
|
Header
|
|
========================================
|
|
|
|
| ``sprout/algorithm/min.hpp``
|
|
| Convenience header: ``sprout/algorithm.hpp``
