With proper rounding to two places, .0864 is equal to .09.

And .0864 * 14 equals 1.2096, with two-place rounding comes to 1.21

I doubt you will see this behavior change any time soon. But as you see how we are doing the rounding, you should be able to take this into account when doing your own calculations. I think the key would be to choose one method, and stick to that for consistency.

Hope this helps.
