Web多种 bitset 操作( 表 3.7)用来测试或设置 bitset 对象中的单个或多个二进制位。 测试整个 bitset 对象 如果 bitset 对象中有一个或几个二进制位置为 1,则 any 操作返回 true,也就是说,其返回值等于 1; 相反,如果 bitset 对象中二进制位全为 0,则 none 操作返回 true。 WebAug 31, 2010 · I've just retested std::bitset with 65 bits and on my 32-bit Linux it works fine and as expected. Notable exception is the to_ulong() method which throws exception if any set bit would be truncated during the conversion. Now I think about it and that is rather obvious: there is no other way as to prevent application from getting truncated data.
