This is totally new to me.
"When you hit an opponent with a melee or ranged attack, you may choose to deal average damage (rounded down), as if you had rolled exactly the average amount on the damage die or dice."
I just halve the die and put em together, right, so 2d6 is 3+3 and 2d10 is 5+5, right?
1d6 = ((1+2+3+4+5+6)/6)= 3.5--> Rounded down is 3
2d6 = (((1+2+3+4+5+6)/6)*2)= 7 Rounded down is 7
or
2d6 = (((1+2+3+4+5+6)/6)= 3.5--> Rounded down is 3)*2 = 6
Honestly it reads to me like the 7 would be correct, however I can see an argument for the 6.
Basically it depends on where you round and multiply.
Using standard Order of Operations you should multiply before you round so as to achieve more correct numbers. This would mean the 7 was correct.
Okay, so the formula is to add all numbers on the die, divide by the die sides, then multiply for extra dice?
Also, does this affect extra die such as Flaming, Bane or Sneak Attack? Usually it explicitly says no or yes.
Easiest way for me to determine what the average of any particular dice, is to add the highest value of the dice with 1, then divide by 2. So a d10 is 1 + 10 = 11, /2 = 5.5. Once you have the average for one die, multiply that by the total number of dice you need. 3d10 = 16.5 rounded down to 16.

Could you provide a link to the Feat/Spell/Ability granting this effect? I am not familiar with it.
If you do not have a link could you please tell me what book it is in and perhaps I can find it so as to better answer your question.

The pasted text on first post is the feat. I found it on pfsrd.
Measured Response (Combat)
You believe that a conservative but consistent response guarantees success.
Prerequisites: Worshiper of Abadar, base attack bonus +1.
Benefit: When you hit an opponent with a melee or ranged attack, you may choose to deal average damage (rounded down), as if you had rolled exactly the average amount on the damage die or dice. You add your damage bonuses and penalties as normal.

EDIT: Ninja'd... But as it reads, you average all the dice, then add your bonuses after.

After reading the feat on D20pfsrd, I believe that if I am parsing it correctly it would apply to any dice rolled.
This feat is extraordinarily good for a rogue as it guarantees average damage on sneak attack.
It explicitly does not effect any non-rolled sources of damage however.
So for example a rogue with a +1 flaming great sword and 3d6 sneak attack with a +4 strength mod would have the following for damage.
1(Enhancement Bonus) + 6(Two-Handed Strength Bonus) + 3[fire damage](Flaming) + 7(GreatSword) + 10 [precision damage](Sneak Attack) = 14 weapon damage 3 fire damage and 10 precision damage for a total of 27 damage on a successful attack.
This is assuming that the feat is applied independently to different damage sources, which I believe it should be so as to interact correctly with things like DR, Elemental resistance, and immunity/resistance to precision damage/sneak attack.
The average of any die is 0.5 greater than half the number of sides it has. So on a d6, that is 3.5.
Die Avg
d4 2.5
d6 3.5
d8 4.5
d10 5.5
d20 10.5
This is because dice are marked as 1 to n, where n is the number of sides. The major factor being that it does not include a 0 (except on 10 sides die where it actually indicates 10, not 0).
