My Calculator is a versatile Reverse Polish Notation (RPN) calculator implemented in Java. It provides a user-friendly interface for performing various mathematical calculations. This document will guide you on how to use My Calculator both from the command line and integrated development environments (IDEs).
-
Shunting-Yard Algorithm and Reverse Polish Notation (RPN) support for intuitive mathematical expressions.
-
Basic arithmetic operations: addition, subtraction, multiplication, division, and exponentiation.
-
Trigonometric functions: sin, cos, tan, cot, arcsin, arccos, arctan, and arcctg.
-
Logarithmic functions: ln, log10, and sqrt.
-
Error handling for invalid expressions, order of operations, and division by zero.
-
Support for both command-line and IDE-based usage.
To use My Calculator from an integrated development environment (IDE) like IntelliJ IDEA, Eclipse, or others, follow these steps:
-
IDE Setup: Open the calculator.java file within your chosen IDE.
-
Run Configuration: Set up a run configuration for the calculator class and execute it.
-
Interactive Menu: You will encounter the same interactive menu as in the command-line version.
I used the Java 21 version here on an IntelliJ IDE.
To use My Calculator from the command line, follow these steps:
-
Java Requirement: Ensure that you have Java JDK/JRE installed on your system.
-
Compilation: Compile the
calculator.javafile using thejavaccommand: CLI enter: javac calculator.java
###Limitations
My Calculator is designed to handle a broad range of mathematical expressions. However, it is worth noting that the program is newly developed and only moderately tested at best due to time constraints. (17 days) With that, extremely large integers could cause an exception, which should be caught, or in the worst case crash the program.
