Nasm x86 Assembly Calculator

Overview

This project is an advanced calculator written in x64 assembly for Windows. It supports both integer and floating-point operations, including addition, subtraction, multiplication, division, exponentiation, modulus, and trigonometric functions. The calculator allows the user to choose between integer and floating-point calculations.

Features

• Integer Operations:
  • Addition
  • Subtraction
  • Multiplication
  • Division
  • Modulus
  • Exponentiation
• Floating-Point Operations:
  • Addition
  • Subtraction
  • Multiplication
  • Division
  • Modulus
  • Exponentiation
  • Sine
  • Cosine
  • Tangent
  • Square Root

Requirements

• NASM - The Netwide Assembler for assembling the code.
• MinGW-w64 - For linking the object files to create an executable.

Usage

1. Clone the repository:

    git clone https://github.com/kavicastelo/assembly_calculator.git
    cd assembly_calculator
   

2. Assemble the Code: Use NASM to assemble the code into an object file:

    nasm -f win64 CAL.asm -o CAL.obj
   

3. Link the Object File: Use MinGW-w64 to link the object file to create an executable:

    gcc -o CAL.exe CAL.obj
   

4. Run the executable: After successfully building the executable, run it:

    ./CAL.exe
   

5. Using the Calculator:
   • The calculator displays a menu to choose the desired operation.
   • You will be prompted to select between integer and floating-point calculations.
   • Enter the required numbers as prompted.
   • The result will be displayed, and the menu will be shown again for further operations.

Limitations

• The calculator does not support memory storage for recalling previous results.
• Input validation is minimal; incorrect inputs may cause unexpected behavior.
