This paper is a brief review of some general Diophantine results, best approximations and their applications to the theory of uniform distribution.

We provide a generalization of continued fractions to the Heisenberg group. We prove an explicit estimate on the rate of convergence of the infinite continued fraction and several surprising analogs of classical formulas about continued fractions.
We explicit the link between the computer arithmetic problem of providing correctly rounded algebraic functions and some diophantine approximation issues. This allows to get bounds on the accuracy with which intermediate calculations must be performed to correctly round these functions.
We fill a gap in the proof of a theorem of our paper cited in the title.
There are two mistakes in the referred paper. One is ridiculous and one is significant. But none is serious.
Consider the group over the ring of algebraic integers of a number field . Define the height of a matrix to be the maximum over all the conjugates of its entries in absolute value. Let be the number of matrices in with height bounded by . We determine the asymptotic behaviour of as goes to infinity including an error term,with being the degree of . The constant involves the discriminant of , an integral depending only on the signature of , and the value of the Dedekind zeta function...
