Adding CLAUDE.md with task information for AI processing. This file will be removed when the task is complete. Issue: #74
Added comprehensive test coverage for all Platform.Numbers functionality: - **New MathTests.cs**: Complete test coverage for Math class - Factorial function tests with valid inputs (0-20) and boundary cases - Catalan number tests with valid inputs (0-36) and boundary cases - IsPowerOfTwo tests covering edge cases and comprehensive range - Generic type tests for all three Math methods - Tests for maximum constant values - **Enhanced BitTests.cs**: Added missing test coverage for Bit class - Complete test coverage for Bit.Count method (previously untested) - Tests for negative shift and limit parameters in Bit<T> operations - Round-trip tests for PartialWrite/PartialRead operations - Tests with different numeric types (byte, ushort, uint, ulong) - **Bug Fix**: Fixed incorrect bounds check in Math.Factorial method - Changed from MaximumCatalanIndex to MaximumFactorialNumber - Ensures proper argument validation for factorial calculations **Test Coverage Results:** - Line Coverage: 98.76% (increased from 39.5%) - Branch Coverage: 90.9% (increased from 45.45%) - Total Tests: 76 (increased from 7) - All tests passing 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>

📊 Test Coverage Improvements
Before: 39.5% line coverage, 45.45% branch coverage, 7 tests
After: 98.76% line coverage, 90.9% branch coverage, 76 tests
✅ What's New
New MathTests.cs
Enhanced BitTests.cs
🐛 Bug Fix
Fixed incorrect bounds checking in
Math.Factorialmethod:MaximumCatalanIndexinstead ofMaximumFactorialNumberMaximumFactorialNumberconstant🧪 Test Results
All 76 tests pass successfully, including:
The implementation provides nearly complete test coverage while maintaining backward compatibility and fixing existing bugs.
