【问题描述】:
所以我正在尝试制作一个脚本,其中用户输入他们需要旅行的英里数和他们每小时旅行的英里数,脚本输出他们必须旅行的剩余小时数和分钟数。我一直在尝试使用 % 来查找剩余的行驶里程/MPH,但它输出了错误的数字。无论如何只能从两个相除的数字中得到小数吗?例如,如果我做 100/65,我得到大约 1.538 的输出,我只想使用 0.538。但是当我使用 100%65 时,我得到 35。这是我当前的脚本供参考:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace TimeCalculator
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Welcome to the Travel Time Calculator");
string answer;
//creates variable for the answer
do
//creates loop to continue the application
{
string grade;
//Console.WriteLine(100-(int)((double)100/65)*65);
Console.WriteLine(" ");
Console.Write("Enter miles: ");
Decimal val1 = Convert.ToDecimal(Console.ReadLine());
//converts input to decimal allowing user to use decimals
Console.Write("Enter miles per hour: ");
Decimal val2 = Convert.ToDecimal(Console.ReadLine());
//converts input to decimal allowing user to use decimals
Console.WriteLine(" ");
Console.WriteLine("Estimated travel time");
Console.WriteLine("Hours: " + (((int)val1 / (int)val2)));
//converts values to integers and divides them to give hours traveled
//double floor1 = Math.Floor(((double)val1/(double)val2));
Console.WriteLine("Minutes: " + (Decimal.Remainder((decimal)val1, (decimal)val2)));
//converts values to double and gets the remainder of dividing both values to find minutes
Console.WriteLine();
//enters one line
Console.Write("Continue? (y/n): ");
answer = Console.ReadLine();
//the string is equal to what the user inputs
Console.WriteLine();
}
while (answer.ToUpper() == "Y");
//if y, the application continues
}
}

两个数字的余数和一个数字的小数部分是两个不同的东西。您正在寻找后者。
