实现计算器为课题 此次设计的计算器应用软件从 visual studio 2012 编程环境中开发 是一 个简单的窗体应用程序 实现简单的计算器功能 以微软自带的计算器为模板 设计了简单 易懂的计算器 这款计算器不仅实现了简单的四则运算的功能 还可以进行复杂数学运算 和进制转换 十进制转二进制 八进制 十六进制 具有简洁的外观 即时准确的获得所需 要要计算的结果 充分降低了数字计算器的难度和所需要的时间 对人们生活和学习具有有 很大的帮助 2 2 系统设计系统设计 1 1 功能设计 功能设计 本计算器由四大模块 分别为 1 标准计算器 即为主窗口 2 科学型计算器 3 程序员计算器 进制转换 4 开发者介绍 2 2 界面设计 界面设计 主窗口界面 from1 2 科学型计算器界面 from2 程序员界面 from3 3 开发者介绍 from4 2 2
