I'm guessing it's missing the return at the end of the output.

The random benchmark uses
printf "%.9f\n", gen_random(100.0)
and gets correct output

Try changing the printf line so you have

#!/usr/bin/ruby

n = (ARGV[0] || 10000000).to_i

partialSum = 0.0
(1..n).each {|i| partialSum += (1.0 / i) }

printf "%.9f\n", partialSum
