如何将100.00转换为100并将100.23转换为100.23省道

num1 = int(100.00)
print(num1)  # 输出结果为100

double num2 = 100.00;
int num3 = (int) num2;
System.out.println(num3);  // 输出结果为100

double num4 = 100.00;
int num5 = static_cast<int>(num4);
cout << num5;  // 输出结果为100

num6 = 100.23
print(num6)  # 输出结果为100.23

double num7 = 100.23;
System.out.println(num7);  // 输出结果为100.23

double num8 = 100.23;
cout << num8;  // 输出结果为100.23
