significant digits (PR#9682)
Duncan Murdoch:
The number 0.12345 is not exactly representable, but (I think) it is represented by something slightly closer to 0.1235 than to 0.1234.
I like using formatC for checking such things. On my (Linux) system, I get: $ formatC(.12345,digits=50) [1] "0.12345000000000000417443857259058859199285507202148"
So it looks as though Windows gets it right.
