std::experimental:: gcd

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.
