Question

我正在尝试制作一个将英寸转换为英尺的程序，并返回英尺数和剩余英寸数（如果有的话）。我试过这个：

public class Convertor
{
/**
 * Fields
 */
    private int inches;
    private int feet;
    private int yards;
    private int leftoverInches;

    /**
     * Constructor for objects of class Convertor
     */
    public Convertor()
    {
        inches=0;
        feet=0;
        yards=0;
        leftoverInches=0;
    }

    /**
     * Mutator method to convert inches to feet
     */
    public void convertValuesInchtoFeet(int anyInches)
    {
        inches=anyInches;
        feet=(anyInches * 0.083);
        leftoverInches= inches%feet;
        System.out.println(inches+" inches = " +feet+" feet.");
        System.out.println("There are " +leftoverinches +"  leftover inches");

    }

不起作用。

有人帮我这个，拜托！谢谢。

Answer 1

试试这个：

public void convertValuesInchtoFeet(int anyInches)
    {
        inches = anyInches;
        feet = Math.floor(inches/12);
               //if int than no need for the Math.floor()
        leftoverInches = inches%12;
        System.out.println(inches + " inches = " + feet + " feet.");
        System.out.println("There are " + leftoverInches + " leftover inches");

    }

Answer 2

int inches = 34;
int feet = inches / 12;
int leftover = inches % 12;
System.out.println(feet + " feet and " + leftover + " inches");

Answer 3

您的代码不起作用的主要原因是因为您正在执行

leftoverInches = inches%feet;

假设你给它13英寸。你有脚= 1（13 * 0.083向下舍入），英寸= 13％1 = 0.你的意思是

leftoverInches = inches%12;

13,13％12 = 1，这确实是剩余英寸的数量。

较小但仍然很重要的错误是你乘以0.083，这不是1/12，并且会给你严重的不准确性。例如，如果输入1,000,000英寸，您将获得

1000000 * 0.083 = 83000 feet

但是

1000000 / 12 = 83333 feet rounded down

所以你会有333英尺的距离。
