mathfuncs-parse 1.1.1

A small module for parsing and evaluating expressions of any number of variables

• valid() -> bool

  • Checks whether the expression is syntactically correct.

• eval() -> float

  • Evaluates the expression. Note: only works if no variables are present.

• eval(vars: dict{str: float|int}) -> float

  • Evaluates the expression, substituting the variables present with the values passed in the dict.

• vars() -> dict{str: float}

  • Returns a dict containing all variables that must be passed to eval().

• add_func(name: str, func: <functionObj(float) -> float>) -> Null

  • Adds a user defined function to the objects internal state. Note: calling ‘init(str)’ does not reset this.

• avail_funcs() -> dict{str: <functionObj>}

  • Returns a dict of available functions which can be used in the current expression.
