Metadata-Version: 2.1
Name: plusminus
Version: 0.2.0
Summary: 
        +/- plusminus is a module that builds on the pyparsing infixNotation helper method to build easy-to-code and 
        easy-to-use parsers for parsing and evaluating infix arithmetic expressions. plusminus's ArithmeticParser 
        class includes separate parse and evaluate methods, handling operator precedence, override with parentheses, 
        presence or absence of whitespace, built-in functions, and pre-defined and user-defined variables, functions, 
        and operators.

Description: # plusminus
        
        The **plusminus** package provides a ready-to-run arithmetic parser and evaluator, based on `pyparsing`'s 
        `infixNotation` helper method.
        
        Strings containing 5-function arithmetic expressions can be parsed and evaluated using the `BasicArithmeticParser`:
        
            from plusminus import BasicArithmeticParser
            
            parser = BasicArithmeticParser()
            print(parser.evaluate("2+3/10"))
        
        The parser can also return an Abstract Syntax Tree of `ArithNode` objects:
        
            parsed_elements = parser.parse("2+3/10")
        
        Arithmetic expressions are evaluated following standard rules for operator precedence, allowing for use of parentheses `()`'s 
        to override:
        
            ()
            ∩ (set intersection)
            ∪ (set union)
            -
            **
            * / × ÷ mod
            + -
            < > <= >= == != ≠ ≤ ≥
            in ∈ ∉
            not
            and ∧
            or ∨
            ? : (ternary)
        
        Functions can be called:
        
              sgn    min  asin  rad    lcm
              abs    max  acos  deg    gamma
              round  str  atan  ln     hypot
              trunc  sin  sinh  log2   nhypot
              ceil   cos  cosh  log10  rnd
              floor  tan  tanh  gcd    
        
        
        The Basic ArithmeticParser also supports assignment of variables:
        
            r = 5
            area = π × r²
        
        This last expression could be assigned using '@=' formula assignment:
        
            area @= π × r²
        
        As `r` is updated, evaluating `area` will be reevaluated using the new value.
        
        
        Custom expressions can be defined using a simple API. Example parsers
        are included for dice rolling, combination/permutation expressions, and 
        common business calculations. These parsers can be incorporated into
        other applications to support the safe evaluation of user-defined 
        domain-specific expressions.
