Question

大家好我有一个1到1000个数字的数组

int[] Numbers={1,2,3,4,5,6............1000};    
float CalculatedBy=3.5;

我希望通过CalculatedBy值（上面的浮点变量）将商和剩余值输入数组

我的代码：

首先，我将此数组拆分为char数组

    Char[] splitNumbers=Numbers.split(",");

    foreach( int charNumber in splitNumbers)
    {

    if(charNumber % CalculatedBy==0 )
    {
    //i know i am totally going to wrong way So what will i do ? 
    }    
}

我的主要条件是：

我想在控制台窗口中使用此格式编写商数和剩余值

价值1：   结果是：Q为1，R为1

值2：   结果是：Q为1，R为1

我不想显示剩余的值是0。

Answer 1

您可以使用以下代码：

int[] Numbers = { 1, 2, 3, 4, 5, 6, 7, 8 };
float CalculatedBy = 3.5F;

foreach (int number in Numbers)
{
    if (number % CalculatedBy != 0)
    {
        int quotient = (int) Math.Floor(number / CalculatedBy);
        float remainder = number - quotient * CalculatedBy;
        Console.WriteLine("Value {0}: Result is : Q is {1} and R is {2}", number, quotient, remainder);
    }
}

Answer 2

您无需转换为char数组，

int[] Numbers = { 1, 2, 3, 4, 5, 6, 7, 8 };
float CalculatedBy = 3.5F;

foreach (int n in Numbers)
{
    if (n % CalculatedBy != 0)
    {
        int q = (int) Math.Floor(n/ CalculatedBy);
        float r = n- q * CalculatedBy;
        Console.WriteLine("Value {0}: Result is : Q is {1} and R is {2}",n,q,r);
    }
}

Answer 3

当使用整数而不是浮点数时，另一种方法是使用Math.DivRem方法。

int[] Numbers = { 1, 2, 3, 4, 5, 6, 7, 8 };
int CalculatedBy = 3;

foreach (int number in Numbers)
{
    if (number % CalculatedBy != 0)
    {
        int remainder;
        int quotient = Math.DivRem(number, CalculatedBy, out remainder);
        Console.WriteLine("Value {0}: Result is : Q is {1} and R is {2}", number, quotient, remainder);
    }
}
