An explicit representation of a piecewise rational interpolant with quartic numerator and quadratic denominator is presented. For positivity data, monotone data and convex data, the shape-preserving properties of the interpolant are given. The interpolant is C 2 continuous spline with a shape parameter w i on each subinterval. The values of w i to guarantee shape preservation are estimated. A convergence analysis establishes an error bound in terms of w i and shows that the interpolant is O (h 2) or O (h 3) accurate. Several examples are supplied to support the practical value of the given interpolation method.
