Macro question

Can anyone tell me how to tell this operation to round down?  /?{Prim or 2nd|} There is something under this:  floor(x)  rounds x towards negative infinity.   But I am not sure how to use that. 

Just put the floor() around any calculation: [[ floor(3/2) ]] What does your full macro look like?

Hi Ziechael, Here it is: /me Attacks with @{Weapon_1} attack roll hits or misses by [[(@{Raw_BCS_1}+@{level}+@{Quality_1}+@{Special_Hit_Mod_1}-?{Armor Class|0}+?{Situational Modifier|0})/?{Prim=1 or 2nd=2|1}-1d20]] It adds several modifiers to the RAW BCS then subtracts AC adding situation modifiers. Then what happens is if you change the /?{Prim=1 or 2nd=2|1} to a "2" it halves the number. I want it to half that number rounding down. What it does now it gives fractional numbers.  Example:   BCS 14+2+1+0-10    would be 14 skill +2 level +1 quality weapon +0 special modifiers -Armor class +/- Situational modifers.  So in this example:   14+2+1+0 = 17 - 8AC +/- 0 situational  = 9  .... the last part of the macro if you place a 2 in the box it divides it by 2.  So in this case it would be 4.5. Id like it to know to round down on those fractions. Thanks for the input in advance Ara

Try [[floor((@{Raw_BCS_1}+@{level}+@{Quality_1}+@{Special_Hit_Mod_1}-?{Armor Class|0}+?{Situational Modifier|0})/?{Prim=1 or 2nd=2|1})-1d20]] adding floor(     just after the opening inline brackets, and ) just before the -1d20. (You could put it just before the ending brackets too.) You might change that Prim at the end from ?{Prim=1 or 2nd=2|1} to ?{Which Attack|Primary,1|Second,2} To give a drop down (change the labels as needed)

Outstanding! worked perfectly ... thank you very much.

The main thing to remember if you use the player input query is that if they accidentally put 0 or leave it blank you may end up with a divide by 0 error. GiGs suggestion of a drop down query is much safer and limits the potential for player induced headaches ;)

Did I ever, took me a long time to figure out why the macro worked for a bit and then it failed after a few tries .... the 0 error. Will never forget again.
