Note that counting in integers will work fine, and so should counting by
fractions that are non-repeating decimals in binary, such as .25, .125, and
.0625.

Of course the integers you can handle accurately with a double type are
quite big (several thousands of millions...).

Now *there's* a phrase to cause anxiety in an American listening to an
international audience.

I had a discussion at work here about that once:
In the US:
million = 10^6
billion = 10^9 (thousand million)
In UK:
million = 10^6
billion = 10^12 (million million)

I know the 'billion' problem in the UK/US, so I deliberately used the
term "thousands of millions" instead. I don't know how good it sounds, but
I don't care; I don't want to cause confusion.

If you take a million one thousand times, how much do you get?-)
