Changed

  • Operators priority is now from lowest (0) to highest (int.Max);

  • Removed some deprecated operation aliases (degrad and raddeg).
  • Removed some deprecated functions related to unnamed contexts :
    • Constructor Interpreter(IInterpreterContext).
    • Function SetContext(IInterpreterContext).

Fixed

  • Operators that contain digits in their names no longer fail (e.g.: deg2rad).

[0.2.0-alpha] - 2017.08.29

Added

  • The interpreter now handles the use of multiple contexts (identified by name).

  • Copies of all previously prcessed formulae are now kept in cache (optimization).

Changed

  • Operations and values are now stored a tree (optimization).

Fixed

  • Fixed precedence issues related to | and & boolean operations. 2`).

Deprecated

  • Constructor Interpreter(IInterpreterContext) is now deprecated. Use Interpreter.SetContext(string, IINterpreterContext) instead.
