std::experimental::lcm

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

Computes the least common multiple of the integers m and n.

Contents

[edit] Parameters

m, n - integer values

[edit] Return value

If either m or n is zero, returns zero. Otherwise, return the least common multiple of |m| and |n|.

[edit] Remarks

If either M or N is not an integer type, the program is ill-formed.

The behavior is undefined if

  • |m| is not representable as a value of type M; or
  • |n| is not representable as a value of type N; or
  • the least common multiple of |m| and |n| is not representable as a value of type std::common_type_t<M,N>.

[edit] Exceptions

Throws no exceptions.
