复利计算的单元测试
此次测试只用两个单元作为例子
结果截图:
源代码:
public class testMoney { public double danli(double P ,double i,double N ){ double M; for (int j = 0; j < N; j++) { P = P * (1 + i); P = P + N; } M= Math.round((P - N) * 100) / 100.0; return M; } public static double moneyzz(double P, double i, double N, double T) { double F; for (int j = 0; j < N; j++) { P = P * (1 + i); P = P + T; } F = Math.round((P - T) * 100) / 100.0; return F; } }
