Negative results = automatic convert to a "0"

Hello I would like to know what is the formule, if any, to tell the macro to automatically show a "0" if the result is a negative number. (for example when the results of an attribute from two opponents are negative..I just need a "0") thanks for the enlightment !

{0, @{target|Attribute}}kh1 ought to work.

Yeah well it doesnt work .. I explained myself wrong (but I expected an explanation, not a pre-made formula :) ) here is my actual formule : [[ ?{Initiative @{target|character_name}|0} - ?{Initiative @{selected|character_name}|0} ]] where I want the final result to show 0+ only. No negative.

That I think will take the API to do. Skimmed through the wiki and couldn't find anything to suggest.

Put the whole mess into a roll comparison and add a 0d0 to the two groups to meet the roll requirement. (KH comparisons need to include some kind of roll) [[ {0d0 , 0d0 + ?{Initiative @{target|character_name}|0} - ?{Initiative @{selected|character_name}|0} }kh1 ]] Will result in a positive value if the first query is greater, and a zero if the first query is lower than the second.

Mark G. said: KH comparisons need to include some kind of roll No they don't. They simply can't mix math and rolls (you must have only math values or only rolls). This works perfectly fine, I just tested it: {0,?{Initiative @{target|character_name}|0} - ?{Initiative @{selected|character_name}|0}}kh1 It can be used in either an inline roll or a regular /roll command.

Great thanks a lot !!!!

"...where I want the final result to show 0+ only. No negative." If the result is greater than zero, leave it. If it's less than zero, make it zero.

If your group is {0, targetInitiative - selectedInitiative} and you're keeping the highest 1 value, you will get 0 if the initiative difference is negative (because 0 is higher than all negative numbers) or the initiative difference if it's positive (because all positive numbers are higher than 0).
