v0.2.0

Major Additions

• Integer division (with //), modulo, lcm, and gcd operations
• Floor, ceiling, rounding, and random operations
• New abstract classes for new integer operations
• Settings to enforce functions' domain and range when simplifying using inverse functions
• Array indexing to retrieve values from methods like solve

Minor Additions

• Make parsing errors more descriptive
• Port parsing to use operation maps rather than operation lists
• New test class for integer operations
• Many new exceptions for improved error handling
• Support for _ in evaluate (used as eval x^2 x=_ when _ is a Double)
• Better handling of ArrayIndexOutOfBoundsExceptions in the keyword interface
• err command to improve error reporting
• version command
• reset command

Changes

• Restrict variable and function names to a regex of valid names to improve multi-character name support
• Change equals to check if two functions are exactly equal and implement equalsSimplified to check if they are equal when simplified
• Make substitute/sub more powerful in the keyword interface by allowing the substitution of multiple expressions simultaneously
• Make def and sub in automatically perform a minimalSimplify
• Move SettingsParser functionality directly to Settings
• Rename SpecialFunction to EndpointFunction
• Improve exit logic from all interfaces

Bugfixes

• Fix toInteger error message using the wrong margin from Settings
• Fix bad rounding in ParsingTools.toInteger and ParsingTools.isAlmostInteger
• Fix the evaluation of several arctrig functions
• Fix parsing of non-escaped expressions with spaces such as 1 + sin(x)
• Fix defconstant not LaTeX-escaping constant names
• Add an exception when user attempts to use nested quotes in keyword interface
• Fix division by decimals such as 1/.2 not working properly
