Scientific Calculator Project: Design and Implementation

Desklib provides past papers and solved assignments for students. This project details the creation of a scientific calculator application.

Scientific Calculator
Abstract
“Scientific Calculator” helps in doing higher scientific calculation within a second. This project is able
to solve various types of mathematical problems like logarithmic, trigonometric etc. Basically, this
calculator is designed for doing that calculation which are not able to do by the basic calculators and are
useful for calculating engineering calculation. This calculator supports various mathematical functions
like Floor value, ceiling value also.
By developing this calculator hard complex calculation is completed with ease. The big calculation can
be performed by this calculator.
Introduction
This calculator is used for performing large calculations. It is very effective in solving the higher degree
engineering problems within a second. Various mathematics predefined functions are supported by this
calculator. The result one will get from this calculator is accurate to the six decimal places.
Motivation
While finding complexities in doing mathematical calculation of higher order. I thought to design a
system which is able to perform all these complex calculations easily. This calculator helps to solve
higher order mathematical function in an easy way.
System structures
Hardware requirements for the system:
Hard disk: 20GB, RAM: 2 GB (minimum), CPU: dual-core
Software requirements for the system:
Java 8 (Kordelakos, 2019), NetBeans (Juneau, 2018).
Functions
a) Help to solve complex mathematical problems.

b) Mathematical functions are easily solved by this calculator like logarithmic, trigonometric,
ceiling, floor, exponential etc.
c) Maths error can be detected by this calculator.
User requirements
The designed system can be run on any system has Java installed in it. If any IDE NetBeans (most
preferable) is present in the system, then it is good. But strict requirement is only java installed in the
system.
Additional feature
a) This calculator is able to store some previous values as history.
b) One can change the input type from the calculate for performing trigonometric function. Degree
or radian any type can choose from option.
Inherent complexities and challenges
To design the GUI for the calculator and managing all the events on the button is the main challenge in
developing the desired system.
Project Plan
Items Activity date range Activities
1. Week 1 Research for the system.
2. Week 2 – Week 3 Finding all the requirements.
3. Week 4 – Week 6 Developing the whole system.
4. Week 7 Remove bugs, debugging etc.
Conclusion
This developed application is used to solve the critical higher order mathematical problems. Application
has a very interactive graphical design which attracts user. In this developed calculator user finds very
easy to perform all the engineering or scientific calculations.
