Hi All, Another beginner here! I am trying to create a list based around a polynomial. In particular, I want to work with a large-ish number based on a power of 2 e.g. 629 x^2 + 863 x + 271 where x = 2^10 What I want to do is take a number y such as y=6718213 and derive a list where the list values are the coefficients of the polynomial. So that if my number y=1027 (2^10 +3) the polynomial would be x+3 and the list would be { 1,3 } I have tried NestWhileList[] and PolynomialRemainder[] but I'm really struggling to get them to do what I want. I have a procedural programming background; functional programming looks excellent, I just can't get it to work! Any suggestions (like you're using the wrong functions, try these others....) would be gratefully received. I'm also looking to convert the list back into a number once I've finished working with the polynomial. Mathematica v4.2, although it probably doesn't make a lot of difference. Thanks in advance, Alan
