Published source code in the article by Dann Corbit in which he 
approximates the value of an integral is an important kind of 
calculation that's not nearly as you think. Dann shows how simple 
it is to get good results, then discusses some new techniques 
that offer even better accuracy. Also see AA1096.ZIP.
