Of the single decimal digit numbers, 20% are exact (x.0 and x.5, for not
huge x). For two decimal places, it's down to 4% (x.00, x.25, x.50,
x.75) and it spirals quickly downward from there.
Bill Gates got this right in the early days, delivering two Basic
interpreters: binary floating point for speed, and decimal floating
point for money and such. (I never looked at how well his interpreters
did...I just used them.)
