Preliminaries Introduction This book like its predecessor edition is supposed to teach you methods of numerical computing that are practical efficient and insofar as possible elegant. We presume throughout this book that you the reader have particular tasks that you want to get done. We view our job as educating you on how to proceed. Occasionally we may try to reroute you briefly onto a particularly beautiful side road but by and large we will guide you along main highways that lead to practical destinations. Throughout this book you will find us fearlessly editorializing telling you what you should and shouldn t do. This prescriptive tone results from a conscious decision on our part and we hope that you will not find it irritating. We do not claim that our advice is infallible Rather we are reacting against a tendency in the textbook literature of computation to discuss every possible method that has ever been invented without ever offering a practical judgment on relative merit. We do therefore offer you our practical judgments whenever we can. As you gain experience you will form your own opinion of how reliable our advice is. We presume that you are able to read computer programs in C that being the language of this version of Numerical Recipes Second Edition . The book Numerical Recipes in FORTRAN Second Edition is separately available if you prefer to program in that language. Earlier editions of Numerical Recipes in Pascal and Numerical Recipes Routines and Examples in BASIC are also available while not containing the additional material of the Second Edition versions in C and FORTRAN these versions are perfectly serviceable if Pascal or BASIC is your language of choice. When we include programs in the text they look like this include define RAD void flmoon int n int nph long jd float frac Our programs begin with an introductory comment summarizing their purpose and explaining their calling sequence. This routine .
