In the United Kingdom, the national lottery has so far raised several billions of pounds for Good Causes, a programme which distributes money via grants. 28% of lottery revenue goes towards the fund, along with all unclaimed prizes. Additionally, 12% goes to the
Completeness of the real numbers "n"th term in the sequence is the "n"th decimal approximation for pi. Though this is a Cauchy sequence of rational numbers, it does not converge to any rational number. (In this real number line, this sequence converges to pi.) Cauchy completeness is related to the construction of the real numbers using Cauchy sequences. Essentially, this method defines a real number to be the limit of a Cauchy sequence of rational numbers. In mathematical analysis, Cauchy completeness can be generalized to a notion of completeness for any metric space. See complete metric space. For an ordered field, Cauchy completeness is weaker
