Hi folks. I am trying to write a program that does Gaussian quadrature in C. The problem is, the zeros of the Legendre polynomials and their associated weights are made up of at least 21 digits( the fraction ). Is it necessary to use all these digits? If so, how do I represent these numbers in C? If not, do I truncate or round or what? By the way, I am getting these numbers from a table in "Abramowitz & Stegun: Mathematical Functions & Tables". Please send mail via Internet: ndimas@pikes.denver.colorado.edu Thank You Nicholas Dimas
