摘要
说起计算器,值得我们骄傲的是,,,也有用木头,,明代时的珠算盘已经与现代的珠算盘几乎相同. 17世纪初,英国数学家纳皮尔发明的"纳皮尔算筹",英国牧师奥却德发明了圆柱型对数计算尺,这种计算尺不仅能做加减乘除、乘方、开方运算,甚至可以计算三角函数,指数函数和对数函数,这些计算器为现代计算器发展奠定了良好的基础,成为现代社会应用广泛的计算工具. 1642年年仅19岁的法国伟大科学家帕斯卡引用盘的原理,发明了第一部机械式计算器,但是只能做加减计算。1694年,莱布尼兹在德国将其改进成可以进行乘除的计算。此后,一直要到1950年代末才有电子计算器的出现。本文详细论述了一个用C#设计编写的科学计算器的软件设计过程,它具有较强的可操作性及方便性,可以进行加减乘除以及小数运算。具有简单,方便,快捷的特点。

ABSTRACT
Speaking of the calculator, worthy of our putational tools the earliest born in China. A calculation tool in ancient China, the earliest use of that plan, also calledon the whole. The bones much made of bamboo, wood is also useful, animal bone as material. Until today still use theabacus is Chinese another invention ancient calculationtool inthefieldof MingDynasty, the abacus abacus hasand modern are almost the same. In early seventeenth Century, the British mathematician Napier invented"Napier ", aBritishvicar China; Ocurd invented thecylindrical on the number of rule, this rule not only can add, subtract, multiply and divide, square, square root operation, even can calculate trigonometric function,exponential function and logarithmic function, has laid a good foundation for the development of the moderncalculator calculator, computing tools in modern societyhas e widely used. In the 1642 year only 19 years old the great French scientistPascal reference discprinciple,inventedthe first mechanical calculator, but can only doaddition and subtraction. In 1694, Leibniz in Germany will improve thecalculation canbe carried out and , always appears with an electronic calculator tothe late 1950's. This paper discusses in detail the softwaredesign process of a program design with C# scientific calculator, it has strong operability and convenience, canadd, subtract, multiply and divide and decimal simple, convenient, fast characteristics.
