三角算法 200 刻度有规律 注意tk好像是双份

#include <iostream>


int main()
{

    double a, b;

    a = 14.555555555555f;
    b = 6.55555555555f;

    double angleA = a / (a + b);
    double angleB = b / (a + b);
    double coprel = ((a + b) - (a * angleA) - (b * angleB)) * 0.50f + (a * angleA) + (b * angleB);



    std::cout << coprel;
}

 

 

 

看C+TK等不等于A+B就对了 要是等于那准了
