which says amongst other things
     All R platforms are required to work with values conforming to the
     IEC 60559 (also known as IEEE 754) standard.  This basically works
     with a precision of 53 bits, and represents to that precision a
     range of absolute values from about 2e-308 to 2e+308.
and reminds us that

will give you the parameters of the 'double' type.
