# Description of Changes This pull request refactors and improves the logic for converting human-readable size strings (like "10MB", "2.5GB") to bytes in the `GeneralUtils` utility class. The main enhancement is switching from imprecise floating-point arithmetic to `BigDecimal` for more accurate and robust conversions, and centralizing the conversion logic to reduce code duplication and improve maintainability. **Improvements to size conversion logic:** * Replaced all floating-point arithmetic in `convertSizeToBytes` with `BigDecimal` operations to ensure precision and to handle large values more safely. * Introduced a new private method `toBytes(BigDecimal value, int powerOf1024)` to centralize and standardize the conversion from size units to bytes, including error handling for negative and excessively large values. * Added constants `KIB` and `LONG_MAX_DECIMAL` for improved readability and maintainability of size calculations. * Added a helper method `parseSizeValue(String value)` to consistently parse size values as `BigDecimal`. * Updated imports to include `BigDecimal` and `RoundingMode` for the new conversion logic. --- ## Checklist ### General - [ ] I have read the [Contribution Guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md) - [ ] I have read the [Stirling-PDF Developer Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/DeveloperGuide.md) (if applicable) - [ ] I have read the [How to add new languages to Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md) (if applicable) - [ ] I have performed a self-review of my own code - [ ] My changes generate no new warnings ### Documentation - [ ] I have updated relevant docs on [Stirling-PDF's doc repo](https://github.com/Stirling-Tools/Stirling-Tools.github.io/blob/main/docs/) (if functionality has heavily changed) - [ ] I have read the section [Add New Translation Tags](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md#add-new-translation-tags) (for new translation tags only) ### Translations (if applicable) - [ ] I ran [`scripts/counter_translation.py`](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/docs/counter_translation.md) ### UI Changes (if applicable) - [ ] Screenshots or videos demonstrating the UI changes are attached (e.g., as comments or direct attachments in the PR) ### Testing (if applicable) - [ ] I have tested my changes locally.
