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

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

Parameters

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|.

Remarks

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.

Exceptions

Throws no exceptions.
