Math.Pow给人＆QUOT;无法隐式转换类型'双'到'浮动'＆QUOT;错误 [英] Math.Pow gives "Cannot implicitly convert type 'double' to 'float' " error

问题描述

在这个节目，我想创建一个简单的计算器。不过，我似乎无法找到一个方法达到 Math.Pow 线时要克服上述错误。

 命名空间BinaryCalc
{
    类二进制
    {
        公共静态无效的主要（）
        {        INT加法，减法;
        浮分裂，增殖，电力，开方;        INT X;

        X = 10;
        Y = 7;        //Console.WriteLine(\"Please输入对于x）的数;
        //串线=到Console.ReadLine（）;
        // INT X = int.Parse（线）;        //Console.WriteLine(\"Please输入y）的一个号码;
        //字符串LINE2 =到Console.ReadLine（）;
        // INT Y = int.Parse（2号线）;
        此外=（INT）X +（INT）Y;
        减法=（INT）x  - （INT）Y;
        师=（浮点）X /（浮动）Y;
        乘法=（浮点）X *（浮动）Y;        功率= Math.Pow（X，2）;
        开方=的Math.sqrt（x）的;
        Console.WriteLine（加法结果以{0}，补充）;
        Console.WriteLine（减法，在{0}减法的结果）;
        Console.WriteLine（师的结果{0}，除）;
        Console.WriteLine（乘法在{0}相乘的结果）;
        Console.WriteLine（{0}平方在{0}结果，X，功率）;
        Console.WriteLine（{0}的平方根：{0}，X，开方）;        }
    }
}
 

解决方案

Math.Pow使用双击参数。正如错误说，没有的隐的从转换双到浮动，所以转换结果的明确的浮动：

 功率=（浮点）Math.Pow（X，2）;
 

修改结果
修正后的转换顺序

In this program I am trying to create a simple calculator. However, I can't seem to find a way to overcome the aforementioned error when reaching the Math.Pow line.

namespace BinaryCalc
{
    class Binary
    {
        public static void Main()
        {

        int addition,subtraction;
        float division, multiplication, power, sqrt;

        int x;
        int y;
        x = 10;
        y = 7;

        //Console.WriteLine("Please enter a number for x");
        //string line = Console.ReadLine();
        //int x = int.Parse(line);

        //Console.WriteLine("Please enter a number for y");
        //string line2 = Console.ReadLine();
        //int y = int.Parse(line2);


        addition = (int)x + (int)y;
        subtraction = (int)x - (int)y;
        division = (float)x / (float)y;
        multiplication = (float)x * (float)y;

        power = Math.Pow(x,2);
        sqrt = Math.Sqrt(x);


        Console.WriteLine(" Addition results in {0}", addition);
        Console.WriteLine(" Subtraction results in {0}", subtraction);
        Console.WriteLine(" Division results in {0}", division);
        Console.WriteLine(" Multiplication results in {0}", multiplication);
        Console.WriteLine(" {0} squared results in {0}",x, power);
        Console.WriteLine(" Square root of {0} is: {0}", x, sqrt);

        }
    }
}

解决方案

Math.Pow uses a double argument. As the error says, there is no implicit conversion from double to float, so convert the result explicitly to float:

power = (float)Math.Pow(x, 2);

EDIT
corrected the conversion order
