Classes

The following classes are available globally.

  • RatPoly represents an immutable single-variate polynomial expression, as in the examples below.

    AbstractState: RatPolys are sums of RatTerms with non-negative exponents.

    Example RatPolys include 0, x-10, and x^3-2*x^2+5/3*x+3, and NaN.

    Note

    See RatNum’s documentation for a definition of immutable.

    Declaration

    Swift

    public class RatPoly : CustomStringConvertible, Equatable

  • RatPolyStack is a mutable finite sequence of RatPoly objects.

    Abstract State: Each RatPolyStack can be described by [p1, p2, … ], where [] is an empty stack, [p1] is a one element stack containing the Poly ‘p1’, and so on. RatPolyStacks can also be described constructively, with the append operation, ‘:’. such that [p1]:S is the result of putting p1 at the front of the RatPolyStack S.

    A finite sequence has an associated size, corresponding to the number of elements in the sequence. Thus the size of [] is 0, the size of [p1] is 1, the size of [p1, p1] is 2, and so on.
