Annotations of Changes

1. Function Name Changes:

   • Original: EVALUATE, XLMod, SURFACE, DISTANCE, GET_DISTANCE, PERIMETER, TRIBUTARY_AREA
   • Refactored: EvaluateFormula, XLMod, CalculateSurface, CalculateDistance, GetDistance, CalculatePerimeter, CalculateTributaryArea
   • Rationale: Changed to camel case to adhere to common variable naming conventions, improving readability.

2. Variable Name Modifications:

   • Changed variable names (e.g., Z to sheetIndex, X to rowIndex) for better clarity and context.
   • Rationale: Clearer variable names help with maintainability and understanding of the code.

3. Comments:

   • Improved comments for clarity and understanding.
   • Rationale: Clear comments assist future developers in understanding the code's intent.

4. Type Declarations:

   • Added type declarations to the T_Line and T_Point functions for parameters.
   • Specified return types for all functions.
   • Rationale: Enhanced type safety results in fewer runtime errors and clearer contracts for functions.

5. Consistency in Names:

   • Standardized function and variable names (e.g., tColumn, columnValX, etc.).
   • Rationale: Consistency aids readability and comprehension throughout the code.

6. Improved Logic Flow:

   • Reorganized sections to ensure function declarations are grouped logically.
   • Rationale: Logical grouping helps developers and readers navigate the code more easily.

7. General Formatting:

   • Added clear spacing, indentation, and line breaks for better code structure.
   • Rationale: Improved formatting enhances visual appeal and comprehension.

The refactored code maintains original functionality while enhancing readability and maintainability. Further improvements can involve the addition of error handling and testing to ensure robust execution in all scenarios.
