Description
While investigating ousd_analytics, I found a small issue with small numbers:
The user deposited E 0.001 and got OETH 0.000999999999999999
https://etherscan.io/tx/0x9b005270a8ea48d6ea28f9f72550ba814dd579d73c81596eeaa82296ec5544b3
Funny enough, etherscan rounds it up.

Research direction
Start by examining the linked Etherscan transaction and the reported ousd_analytics result for the 0.001 E deposit. Trace where the OETH amount is calculated and identify the intended precision and rounding behavior; the issue is complete when the small-amount conversion no longer loses the reported precision.
