Hi use the logarithmic representation for your problem.
The Brobdingnag package uses such a form in a (more-or-less) user-transparent manner. HTH rksh Marc Jekel wrote:
Dear R Fans, I have a simple probem but cannot find any reference to the soultion. I want to do calculations with small numbers (for max likelihood estimations). The lowest value R is storing by default is 1*10^-323, a smaller numer like 1*10^-324 is stored as a 0. How can I circumvent this problem? Is there a way to define how small a number can be in R. Thanks for a reply in advance, Marc
