11:21 PM Feature #13219: bug in Math.sqrt(n).to_i, to compute integer squareroot, new word to accurately fix it
- I am confused by your solution in comment #3. By your own report, there is no issue for numbers much larger than a single word. But this code is clearly appropriate only for single-word inputs.
