review text: The Discrete Projective Transform (DPT) approximation is a polynomial approximation for a function in an interval. The approximating conditions correspond to requiring that derivatives in the end points of the interval coincide for the function and its approximation. The basis with respect to which the approximant is represented is inspired by the DPT introduced in [\textit{N.D. Dikoussar}, Comput. Phys. Commun. 79, 39--51 (1994)]. The paper describes some numerical experiments and compares them with the u-approximation introduced in [\textit{D. Roy} et al., Comput. Phys. Commun. 78, 29--54 (1993; Zbl 0878.65011)].
