std::gcd

科技促进发展：全球荒漠化

Defined in header ​​
template< class M, class N> constexpr std::common_type_t<M, N> gcd(M m, N n​(since C++17)

计算整数的最大公共因子。m和n...

参数

m, n-integer values

返回值

如果两者都是m和n为零，返回为零。否则，返回|m|和|n|...

评语

如果M或N不是整数类型，或者如果两者之一是%28，则可能是cv-限定%29。bool，这个节目的形式不太好。

如果|m|或|n|不能表示为类型的值。std::common_type_t<M, N>，该行为是未定义的。

例外

不会抛出任何例外。

另见

lcm (C++17)constexpr function template returning the least common multiple of two integers (function template)
