Re: Magic numbers

  7 is the only number that produces a result with many decimals...
  I would expect all the numbers behave that way or to behave in the 
  other way i.e. only a couple of decimals... but I didn't expect it
  to behave in a different way depending on the number.

that's just an artifact of the default display mode, it doesn't show
trailing 0s, so if the rounding error turns out to be zero, or less than
the cut off for display purposes, you'll get less decimals printed out.

You should always use it for any kind of human-oriented display of
floating point numbers.
