是否有可用作变数的vul块?
例如: 我想将第1和第3类分类。 <代码>int为0,double
result is 0,333333
。 然而,我希望这一结果恰好是1/3
,然后在方案的其他方程式中使用。
是否存在与分类相类似的变量(int
), decimal (double
), e.t.c.(正在以类似方式宣布和使用)? 或者,我是否必须亲自发言?
首先,我思考如何使自己成为自己,但我失败了。
Thanks!

不是核心语言,而是有图书馆,例如boost:Rational 。
我不肯定你问什么,但看。
随函附上:
#include <boost/rational.hpp>
boost::rational<int> one(1);
boost::rational<int> three(3);
boost::rational<int> one_third(one / three);
现在没有理性的数字,它将成为零气的 st子的一部分,即零件的正文。 您可尝试boost,或由 yourself撰写。
