Approximation to Irrational Numbers by Rationals,Given a real number ., let [.], the . of ., denote the greatest integer ≤ ., and let {.} = . ? [.]. Then {.} is the . of ., and satisfies 0 ≤ {.} < 1. Also, let ‖.‖ denote the distance from . to the nearest integer. Then always 0 ≤ ‖.‖ ≤ 1/2.

Approximation By Algebraic Numbers,In the first chapters we studied approximation to real numbers by rationals. We now take up approximation to real numbers . algebraic numbers. This is quite different from the questions e.g. considered in Chapter V on approximation . algebraic numbers by rationals.

W. of length ?(B.) = β?(W.), etc. In this way, a nested sequence of compact intervals . is generated, with lengths . It is clear that . consists of a single point.
