The "NumOps" is a versatile tool designed to assist users with number base conversions, binary coded decimal (BCD) conversion, excess 3 code conversion, and arithmetic operations on numbers of the same base. It provides a user-friendly interface and supports bases ranging from 2 to 16.

Key Features:

1. Number Base Conversion:
- The app allows users to convert numbers between different bases, including binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16).
- Users can input a number in any supported base and select the desired target base for conversion.
- The app performs the conversion and displays the result in the chosen base, aiding users in understanding the number representation across different bases.

2. Binary Coded Decimal (BCD) Conversion:
- The app allows converting numbers to Binary Coded Decimal (BCD) format.
- Users can enter a number, and the app converts it into its corresponding BCD representation.
- The BCD representation is displayed to the user, helping them understand how the binary digits are encoded in BCD form.

3. Excess 3 Code Conversion:
- The app supports the conversion of numbers to Excess 3 code.
- Users can input a number, and the app converts it into the corresponding Excess 3 code representation.
- The Excess 3 code representation is displayed, allowing users to observe the transformation of the binary digits into Excess 3 code.

4. Arithmetic Operations on Same Base Numbers:
- The app enables users to perform arithmetic operations such as addition, subtraction, multiplication, and division on numbers of the same base.
- Users can input two numbers and select the desired operation.
- The app operates on the given numbers and presents the result in the chosen base, allowing users to perform calculations and obtain accurate results within the chosen number base.

Overall, the "NumOps" is a comprehensive tool that simplifies number base conversions, facilitates binary coded decimal (BCD) and Excess 3 code conversions, and empowers users to perform arithmetic operations on numbers of the same base. It is designed to enhance users' understanding of number systems and assist in various mathematical tasks requiring conversions and calculations within a specific base.
