Altcoin difficulty question

[amaxr]

Hello,

I am trying to figure out the formula how to calculate expected number of mined coins based on hashrate and difficulty.

I found this formula: http://bitcoin.stackexchange.com/questions/8028/given-the-probability-of-finding-a-block-and-time-taken-can-i-infer-hashrate

The question is that some coins are showing difficulty below 1. But according to bitcoin wiki 1 is minimum difficulty. Also, formula above is broken if diff < 1.

So, what difficulty between 0 and 1 really means? How do I translate it to expected coins?
