Calculator Tool

Overview​

Calculator Tool provides basic arithmetic computation for numeric inputs. Designed for lightweight usage where simple calculations are required without external dependencies or complex configuration.

Supported Operations​

  • Addition
  • Subtraction
  • Multiplication
  • Division

Inputs​

  • Two numeric values (integers or decimals)
  • Selected arithmetic operation

Output​

  • Single numeric result
  • Division returns floating-point result
  • Division by zero must be handled by caller logic

Use Cases​

  • Utility functions inside applications
  • Form validation calculations
  • Demo or learning environments
  • Lightweight automation workflows

Behavior Notes​

  • Does not persist state
  • No rounding applied unless implemented externally
  • Invalid inputs return errors or undefined results depending on implementation

Example​

Input: 8, 2, Division
Output: 4

Limitations​

  • No support for advanced math functions
  • No expression parsing
  • No chaining of operations

Intended Audience​

Developers needing a minimal arithmetic helper for predictable, deterministic calculations.
