gotcha!

ok, i know what you're thinking. this dead horse is double dead..

in the spirit of advancing to a better computing env, shouldn't it be
time for ruby to default to "real" decimal instead of float?

arguments:

  1. ruby using the dot decimal notation, for sure that is a decimal
notation (and ruby is not c)
  2. we remove 99% of deci gotchas
  3. there is always #to_f. we can put it to better use (if you want
speed and not precision).
  4. i wont ask again and again ;-)

kind regards -botp
