      dest

    • isFinite

      boolean isFinite()
      Determine whether all components are finite floating-point values, that is, they are not NaN and not infinity.
      Returns:
      true if all components are finite floating-point values; false otherwise

    • absolute

      Vector2d absolute(Vector2d dest)
      Compute the absolute of each of this vector's components and store the result into dest.
      Parameters:
      dest - will hold the result
      Returns:
      dest

    • equals

      boolean equals(Vector2dc v, double delta)
      Compare the vector components of this vector with the given vector using the given delta and return whether all of them are equal within a maximum difference of delta.

      Please note that this method is not used by any data structure such as ArrayList HashSet or HashMap and their operations, such as ArrayList.contains(Object) or HashSet.remove(Object), since those data structures only use the Object.equals(Object) and Object.hashCode() methods.

      Parameters:
      v - the other vector
      delta - the allowed maximum difference
      Returns:
      true whether all of the vector components are equal; false otherwise

    • equals

      boolean equals(double x, double y)
      Compare the vector components of this vector with the given (x, y) and return whether all of them are equal.
      Parameters:
      x - the x component to compare to
      y - the y component to compare to
      Returns:
      true if all the vector components are equal
