Changelog

[1.1.2] - 2026-05-28

Added

  • Reset Button: Clears the form for new data entry
  • Round Trip Button: Reverses the last conversion by swapping source base and target base, input and output.
  • Audit Button: Basic arithmetic to confirm the results.
  • Random Button: Adds random numbers to the source matrix.

Fixed

  • Multiples Animation Boundary: Fixed a bug in the Step-by-Step animation where carries propagating into leading "padding" cells were terminating the loop prematurely.
  • Dynamic Row Expansion: Carry propagation now correctly resets visibility boundaries and handles row unshifting (new leading digits) with immediate rendering updates.

[1.1.1] - 2026-05-26

Fixed

  • Negative Base Factors: Fixed a critical bug in the Multiples method where BigInt division truncated scaling factors to zero when converting between positive and negative bases.

Improved

  • Honest Boundary Detection: Replaced "cheating" lookahead scans with a metadata-driven approach. Phase 2 now respects boundaries established by input padding and dynamic "draining" during Phase 1.
  • Visual Clutter Reduction: Leading padding cells in the visualizer are now hidden (visibility: hidden) to focus on active digits, and static matrix displays are sliced to show only significant columns.

[1.1.0] - 2026-05-25

Added

  • Visualizer Engine: Dynamic overlay to animate the conversion process step-by-step.
  • Full Matrix Equation: Displaying $N \times T = R$ to show how linear algebra transforms digit blocks.
  • Dual-Phase Normalization (for animation):
    • Phase 1: Left-to-Right Fraction Sweep (clearing denominators).
    • Phase 2: Right-to-Left Carry/Borrow propagation.
  • Leading Zero Handling: Automatic stripping of leading zeros from inputs and results.

Improved

  • Animation Performance: Optimized step-by-step speed by 25% for better UX.
  • UI Robustness: Added scrollable visualization area and sticky close button to prevent overflow issues in the Chrome extension popup.
  • Type Alignment: Ensured the new visualizer correctly handles Rat objects from the matrix engine, matching the core conversion logic.
  • Phase 2 Optimization: Refined significant boundary detection after the Fraction Sweep to skip redundant leading zero checks during Carry Propagation.

[1.0.0] - 2026-01-18

  • Initial release with Offset and Multiples methods.
