[0.1.0] - 2025-11-22 - Initial Release

Added

• Int128: Cross-platform 128-bit signed integer arithmetic
  • Native __int128 support on GCC/Clang for maximum performance
  • Hand-optimized implementation for MSVC using 64-bit operations
  • Full range: -2^127 to 2^127-1
  • Complete arithmetic operators (+, -, *, /, %, unary -)
  • Comparison operators (==, !=, <, <=, >, >=)
  • Type conversions (int32, int64, uint64, float, double, Decimal)
  • String parsing and formatting (fromString(), toString())
  • Bit manipulation (toLow(), toHigh(), toBits())
• Decimal: High-precision decimal arithmetic
  • 96-bit mantissa with 8-bit scale (0-28 decimal places)
  • Up to 28-29 significant digits
  • Exact decimal representation (no binary floating-point errors)
  • Complete arithmetic operators (+, -, *, /, unary -)
  • Comparison operators (==, !=, <, <=, >, >=)
  • Type conversions (int32, int64, uint64, float, double, Int128)
  • String parsing and formatting (fromString(), toString())
  • Mathematical operations (abs(), trunc(), floor(), ceil(), round())
  • State checking methods (scale(), decimalPlacesCount())
  • Cross-type arithmetic (Decimal ↔ Int128 interoperability)
