简易计算器程序源代码

简易计算器程序源代码下面是一个简易计算器程序的源代码，它可以执行基本的四则运算：```python#定义加法函数def add(x, y):return x + y#定义减法函数def subtract(x, y):return x - y#定义乘法函数def multiply(x, y):return x * y#定义除法函数def divide(x, y):if y == 0:return "除数不能为0"else:return x / y#显示菜单print("选择操作:")print("1. 相加")print("2. 相减")print("3. 相乘")print("4. 相除")#获取用户输入choice = input("输入你的选择(1/2/3/4): ")#获取用户输入的两个数字num1 = float(input("输入第一个数字: "))num2 = float(input("输入第二个数字: "))#根据用户选择执行相应操作if choice == '1':print(num1, "+", num2, "=", add(num1, num2))elif choice == '2':print(num1, "-", num2, "=", subtract(num1, num2)) elif choice == '3':print(num1, "*", num2, "=", multiply(num1, num2)) elif choice == '4':print(num1, "/", num2, "=", divide(num1, num2))else:print("请输入有效的选择")```运行这个程序，你将看到一个简易的计算器菜单。

python科学计算器代码Python科学计算器是一种功能强大的工具，可以用于进行各种科学和数学计算。

它可以进行基本的算术运算，如加减乘除，还可以进行更复杂的计算，如指数、对数、三角函数等。

科学计算器还可以处理大型数据集和矩阵运算，进行数据分析和可视化等。

下面是一个简单的Python科学计算器代码示例。

```pythonimport mathdef add(x, y):return x + ydef subtract(x, y):return x - ydef multiply(x, y):return x * ydef divide(x, y):return x / ydef exponentiation(x, y):return x ** ydef logarithm(x, base):return math.log(x, base)def square_root(x):return math.sqrt(x)def sine(x):return math.sin(math.radians(x))def cosine(x):return math.cos(math.radians(x))def tangent(x):return math.tan(math.radians(x))# 用户输入操作符和操作数operator = input("Enter an operator (+, -, *, /, **, log, sqrt, sin, cos, tan): ")while operator not in ['+', '-', '*', '/', '**', 'log', 'sqrt', 'sin', 'cos', 'tan']: operator = input("Invalid operator. Please enter a valid operator (+, -, *, /, **, log, sqrt, sin, cos, tan): ")if operator in ['+', '-', '*', '/']:num1 = float(input("Enter the first number: "))num2 = float(input("Enter the second number: "))if operator == '+':result = add(num1, num2)elif operator == '-':result = subtract(num1, num2)elif operator == '*':result = multiply(num1, num2)else:result = divide(num1, num2)elif operator in ['**', 'log', 'sqrt', 'sin', 'cos', 'tan']:num = float(input("Enter a number: "))if operator == '**':exponent = float(input("Enter an exponent: "))result = exponentiation(num, exponent)elif operator == 'log':base = float(input("Enter a base: "))result = logarithm(num, base)elif operator == 'sqrt':result = square_root(num)elif operator == 'sin':result = sine(num)elif operator == 'cos':result = cosine(num)else:result = tangent(num)print("Result:", result)```这个代码示例中，我们定义了一系列的函数来执行各种不同的计算操作。

超详细一、因为计算器设计的控件太多，不便使用控制台应用程序完成，所以这里使用Windows窗体应用程序，并命名为Calc,如下图所示：二、向窗体中拖入需要的控件，如下图所示：（完成效果图）结果显示区（作者博客左边的文本框）是TextBox控件，并修改其name为txtShow ，按键0~9为Button控件，并将其name分别修改为btn_0、btn_1、btn_2、btn_3、btn_4、btn_5、btn_6、btn_7、btn_8、btn_9；按键【负数】的name值修改为btn_sign，按键【.】的name 修改为btn_dot，按键【+ - * /】的name值分别修改为btn_add、btn_sub、btn_mul、btn_div，按键【=】的name值修改为btn_equ，按键【倒数】的name值修改为btn_rev，按键【平方】的name值修改为btn_sqr，按键【开方】的name值修改为btn_sqrt。

右边的计算器图片空间是PictureBox，作者博客控件是LinkLabel，可以不添加，以上所有控件均可按照需求添加，只保留自己需要的按钮控件和textbox控件即可。

三、代码部分（含解释），采用switch多分支语句编写using System;using System.Drawing;using System.Collections;using ponentModel;usingusing System.Data;namespace Calc{///<summary>///温柔一刀C#简易计算器的实现///</summary>public class CalcFormForm{private Button btn_0;private Button btn_1;private Button btn_2;private Button btn_3;private Button btn_4;private Button btn_5;private Button btn_6;private Button btn_7;private Button btn_8;private Button btn_9;private Button btn_add;private Button btn_sub;private Button btn_mul;private Button btn_div;private Button btn_sqrt;private Button btn_sign;private Button btn_equ;private Button btn_dot;private Button btn_rev;private TextBox txtShow;private Button btn_sqr;private PictureBox pictureBox1;private LinkLabel linkLabel1;///<summary>///必需的设计器变量。
