We consider the question of the approximation of nonnegative functions by nonnegative splines of order k (degree $< k$) compared with approximation by that subclass of nonnegative splines of order k consisting of all those whose B-spline coefficients are nonnegative; while approximation by the former gives errors of order ${h^k}$, the latter may yield only ${h^2}$. These results are related to certain facts about quasi-interpolants.
