[R] Integer precision etc.

[(Ted Harding)]

Thanks to James Holtman for the confirmation of the IEEE definition,
and to Marc Schwartz and Roger Koenker for pointing out ".Machine"
which I had not been aware of!

For the latter, the information I wanted is in

> .Machine$double.digits
[1] 53

so that the largest integer exactly represented is indeed 2^53 -1.

Best wishes to all,
Ted.
