Arity returns the number of argument the operator takes-1 is returned if an undefined symbol is provided

funcFind¶

func Find(textstring) (string,bool)

Find the internal function name for an operator, if the input text is one.

funcFindReverse¶added inv0.3.0

func FindReverse(symbolstring) (string,bool)

FindReverse returns the unmangled, text representation of the operator.

funcFindReverseBinaryOperator¶added inv0.3.1

func FindReverseBinaryOperator(symbolstring) (string,bool)
