A command line calculator which supports mathematical expression with scientific functions is very useful for most developers.Most of the time, I do not feel comfortable with the calculator available with Windows. I needed a calculator which will not restrict writing expressions.
Thus you can get the values of all the variables used in the previous calculations.
- Should display all the option this new designed calculated upon.
- Must calculate mathematical function and displayed the output based on that functions likez:
- Adding, Subtracting, Multiplication, Division
- Power, Square, Cube, Square root
- Round, Ceiling, Floor, Main Value, Max Value
- Trigonometric functions such as sin, Cos, asin, acos,atan
- Exponential function
- alindrome(it must accept at least three digit number as it must ask the number of digit to be entered and then to be then must be check whether the given number is prime or not
- Armstrong number(must check whether the entered number is Armstrong or not.
- Prime number(must calculate whether the number is prime or not
- Average(first take the input the number of entries expected and then calculate the average),
- GCD( of the two number entered by the user)
- LCD( of the two number entered by the user)
- Exit option(to terminate the program).
- Analysis
- Algorithm
- Coding
- Testing
- Documentation
The ExpressionCalculator class has alternative method which returns true if compilation of the source code is successful, This fuction is use to validate the variable name in the Calculator class.
- Our project is only a humble venture to satisfy the needs to manage their project work. Several user friendly coding have also adopted. This package shall prove to be a powerful package in satisfy all requirements of the user. The objective of software planning is to provide a frame work that enable the manager to make reasonable estimate made within a limited time frame at the beginning of the software project and should be update regularly as the project regularly.
