  15. I'm trying to write Icon procedures that implement the approximate <, >, and =
  16. relations for real numbers that are in Knuth Vol. 2, section 4.2.2, p. 218 in
  17. the 2nd ed.
  18.  
  19. It seems to me that to write these efficiently one needs access to the floating
  20. point representation of reals, i.e. fractional part and exponent.
  21.  
  22. Is that possible?  Even better, has anybody already written something like this?
