std::experimental::gcd(3) C++ Standard Libary std::experimental::gcd(3)


std::experimental::gcd - std::experimental::gcd


Defined in header <experimental/numeric>
template< class M, class N> (library fundamentals TS v2)
constexpr std::common_type_t<M, N> gcd(M m, N n);

Computes the greatest common divisor of the integers m and n.


m, n - integer values

Return value

If both m and n are zero, returns zero. Otherwise, returns the greatest common
divisor of |m| and |n|.


If either M or N is not an integer type, or if either is (possibly cv-qualified)
bool, the program is ill-formed.

If either |m| or |n| is not representable as a value of type std::common_type_t<M,
N>, the behavior is undefined.


Throws no exceptions.
