Floating point precision doesn't' really become a program until you get
to rather large or rather small values.  I am not sure what range of
precision the AS/400 gives, but I remember checking it out on PCs and
it was quite impressive (something like 15 decimal places with long
float, 30 places total counting the integer part).
