R 3.2.0
OS X
Colleagues
I received unexpected output from a command issued in a terminal window:
> dput(CI)
c(82.9888290534313, 100.544763749464)
> round(dput(CI), 2)
c(82.9888290534313, 100.544763749464)
[1] 82.98999999999999 100.54000000000001
I expected the result of the second command to be:
82.99 100.54
Interesting, the problem also occurs if I round to 5 or 8 digits.
Of note, the problem does NOT occur in R GUI or in Windows.
I am aware of FAQ 7.31 (Why doesn’t R think these numbers are equal?) but I
don’t see how this could be manifestation of that issue.
I am curious as to the explanation of this issue.
