摘 要：目前，科學(xué)計(jì)算器的應(yīng)用非常廣泛，從科研、生產(chǎn)、國防、文化、衛(wèi)生、直到家庭生活，都離不開科學(xué)計(jì)算器的服務(wù)。通過使用科學(xué)計(jì)算器，避免了人工運(yùn)算的繁瑣，以及人工運(yùn)算可能帶來的較大誤差和運(yùn)算錯(cuò)誤，給人們的運(yùn)算帶來了極大的方便。

這篇文章主要介紹用軟件的方法實(shí)現(xiàn)科學(xué)計(jì)算器系統(tǒng)，包括：科學(xué)計(jì)算器系統(tǒng)的概述，科學(xué)計(jì)算器系統(tǒng)的開發(fā)原理和主要實(shí)現(xiàn)的功能，子模塊的設(shè)計(jì)和實(shí)現(xiàn)技術(shù)。其中，重點(diǎn)介紹了對話框、控件的使用，不調(diào)用庫函數(shù)，通過計(jì)算方法的原理來實(shí)現(xiàn)函數(shù)計(jì)算。

本系統(tǒng)需要實(shí)現(xiàn)以下功能：加、減、乘、除、余運(yùn)算、倒數(shù)、乘方運(yùn)算、開方運(yùn)算、冪運(yùn)算、對數(shù)運(yùn)算、指數(shù)運(yùn)算、正弦函數(shù)運(yùn)算、余弦函數(shù)運(yùn)算、正切函數(shù)運(yùn)算、余切函數(shù)運(yùn)算、反正弦函數(shù)運(yùn)算、反余弦函數(shù)運(yùn)算、反正切函數(shù)運(yùn)算、反余切函數(shù)運(yùn)算、排列組合運(yùn)算和弧度與角度之間的轉(zhuǎn)換，能輸入正負(fù)數(shù)、小數(shù)，具有清零、退格功能，具有連續(xù)運(yùn)算的能力。

Development and implementation of scientific calculator

Candidate:

Supervisor: Associate Professor

Abstract：Currently, the application of scientific calculator is very extensive. It can not be get away from the service of scientific calculator in the field of research, production, national defense, culture, hygiene, even family life. By using scientific calculator, the tedious artificial operation, the larger errors and operational mistakes, which are caused by artificial operation, can be avoided. It brings much convenience to people's operation.

This article mainly introduces a scientific calculator system implementing from the perspective of software. It includes the overview and developmental principle of scientific calculator system. It also contains the primary functions, which have been implemented, the design and implemental technology of sub-modules. Among them, it forces on introducing the usage of dialog box and controls as well as the implementation of mathematic function without using library function, but computing method.

The system needs to achieve the following functions : adds, subtracts, multiplies, divides, the remainder operation, the countdown operation，radicand, power calculation, the log and index calculation, the operation of sine function, cosine function, tangent function, cotangent function, arc sine function, arc cosine function , arc tangent function and arc co
