Can I drop "1" rolls out of exploding dice?

I want to be able to use exploding dice, but have 1s count as zeros.  Is it possible to discard 1s?  I couldn't see a way on the dice rolling page, but I'm just starting to use anything other than the basic rolls, so I could have missed it.  Thanks. 

You cannot discard particular valued dice but there may be a workaround. Can you fully describe (with examples) the dice roll you're attempting?

Ooooh, yes, I can!  Thanks!  I want to be able to roll a set of dice, discard the 1s, and reroll the maximums.  So if I'm rolling 4d4, and I get 1,1,3,4, I would discard the 2 1s, and reroll the 4. So if my reroll was 3, I'd get 10 (3+4+bonus 3=10) If I rolled again and got 1, 3, 4, 4, I would discard the 1 and reroll the two 4s. If they were a 4 and a 1, I'd discard the one and re-reroll the four. If it was a a 2, I'd end up with 17 (3+4+4=11 +bonus 4 +bonus 2=17).  The same thing would be true of any other die. If I was rolling 4d6 I'd reroll the 6s and ignore the 1s.  Does that make sense?   I appreciate any help you can offer! As I said, I'm new to this forum and still finding my way around!  Cheers! 

This macro can handle those cases [[ ?{How Many Dice|4}d?{Die Size|4|6|8|10|12|20}!d?{How Many Dice} + (?{How Many Dice}-[[ ?{How Many Dice}d?{Die Size}=1 ]])d(?{Die Size}-1)r1cs0 ]] It works by splitting the exploding part (the max rolls) and the non-exploding part where 1's are dropped. The actual dropping of 1's is done by the nested roll after which the non-1 and non-max values are rolled

Wow, thanks!  So if I understand correctly, it rolls all of the max rolls first, ignoring anything BUT a max roll (and presumably doing all of the repeat rolls at that time?)  Then it rolls all of the NON max rolls in a separate roll, ignoring 1s?  Do I have that right?  I'm basing this belief on what I'm seeing in the rolls; I don't understand macros enough to follow what's going on there!  Thanks for all of your help! 

You understand correctly
