Detailed Description

Header file defining the FloatIndexVector class for handling floating-point index vectors.

This class is designed to provide a robust and efficient way to handle floating-point vectors with support for hashing and precision control. It is primarily used in the OPAT library for indexing and cataloging data tables.

Design Choices:

• Precision Control: Allows rounding of floating-point values to a specified precision for consistent hashing.
• Hashing Support: Implements a custom hash function for use in unordered containers.
• Flexibility: Supports initialization with or without precision and provides methods for modifying the vector.

Example Usage:

#include "indexVector.h"
 
int main() {
    std::vector<double> vec = {1.2345, 2.3456, 3.4567};
    FloatIndexVector index(vec, 2); // Initialize with precision of 2 decimal places
 
    std::unordered_map<FloatIndexVector, std::string> map;
    map[index] = "Example Data";
 
    if (map.find(index) != map.end()) {
        std::cout << "Found: " << map[index] << std::endl;
    }
    return 0;
}
