closedprintf("%.60f\n", 0.1r) shows 0.100000000000000005551115123125782702118158340454101562500000

Description
printf shows 0.1r (rational) not 0.1 as follows.
% ./ruby -ve 'printf "%.60f\n", 0.1r'
ruby 2.2.0dev (2014-08-15 trunk 47187) [x86_64-linux]
0.100000000000000005551115123125782702118158340454101562500000
It seems printf converts the rational argument to a float.
I expect 0.100000000000000000000000000000000000000000000000000000000000 instead of
0.100000000000000005551115123125782702118158340454101562500000.
