Point

public struct Point : CustomStringConvertible, Equatable

Point instances contain elliptic curve points.

For points in a prime characteristic domain, the x-coordinate and y-coordinate are non-negative integers.

For points in a characteristic 2 domain, the x-coordinate and y-coordinate are binary polynomials where the coefficients (0 or 1) are the bits of the x and y values.
