Hey, they allow MMs & the institutions to trade in the 5th and 6th decimal place for a couple reasons.
1.) Market Makers-it supports liquidity by allowing them to profit from tight spreads, which otherwise they would not be able to make money, and it would deter them from "keeping an orderly market" (technically their job, but we all know they're out here to make $$) i.e. this way a MM can make money selling .0001? when he bought at .0001. They'll usually do something like if its a 1,000,000 share order, sell 990,000 @ .0001 and 10k @ .00015 just so they can make a tiny profit. It also allows them to profit by shorting. BC in the sub penny market .0001 tick can be a 100%, 50%, 33%, 25%,etc. etc. gain. And normally investors are only seeking 5-15% for short term trades.

2.) Options contracts. Either company management, through stock options, or convertible debt holders receive rights or warrants to purchase a stock at say, for ex, 60% of the lowest trading price over the past 30 days, or sometimes its like 60% of the avg. trading price over the last 30 days...hopefully here you can see why the numbers could get ugly, some contracts allow for rounding up to the nearest decimal, while others don't

Anyways that's my two cents. Hope this shed some light for you.
