Roman Numerals Educational

Version 2.4.5 - Vinculum Parsing & Score Accuracy Fixes Bug Fixes: • Fixed a bug in vinculum (overline) Roman numerals where numbers like 4,000 and 9,000 were incorrectly displayed with overlines over the M (rendering as [M-bar][V-bar] and [M-bar][X-bar], representing 1,005,000). They are now correctly displayed as M[V-bar] and M[X-bar]. • Fixed combining overline (vinculum) Unicode parsing. Corrected parser to decode grapheme clusters properly, resolving false negatives when users submitted mathematically correct numbers. • Fixed score and accuracy distortion where streak bonuses were added directly to the correct question count, resulting in mathematically impossible accuracy rates (e.g., 309%). Improvements: • Expanded game bounds up to exactly 1,000,000 ([M-bar]), updating Level 10 ranges and unit tests. • Prevented text truncation on title and progress labels for smaller portrait iPhone screen sizes. This update resolves critical notation and Unicode parsing issues for values >= 4,000, ensuring high-score tracking and accuracy percentages calculate and display correctly.
