review text: The partial sums of trigonometric interpolating polynomials of bounded \(2\pi\) periodic functions are considered. The speed of pointwise and uniform convergence of these sums are evaluated in terms of pseudovariations, variations and modulus of continuity of functions Riemann-integrable over \(<-\pi,\pi >\).
