Some existence results concerning approximate fixed points of the weak contractions introduced by V. Berinde on a metric space (not necessarily complete) are given. We also prove some quantitative theorems regarding the set of approximate fixed points for two subclasses of weak contractions, one of them being the class of Rus-Reich operators.
