Guo (1988) introduced the integral modification of
Meyer-Kö nig and Zeller operators Mˆn and studied the rate of convergence for functions of bounded
variation. Gupta (1995) gave the sharp estimate for the operators Mˆn. Zeng (1998) gave the exact bound and claimed to improve the results of Guo and Gupta, but there is a major mistake in the paper of Zeng. In the present
note, we give the correct estimate for the rate of convergence on bounded variation functions.
