[PF] Help with a class ability macro

Hi, I know nothing about Javascript or CSS so I'm trying to fumble my way through the character sheet for Pathfinder. I'm playing a warpriest and trying to put a macro into the Pathfinder sheet to get my Fervor ability to work. I need it to roll 1d6 for every 3 levels I am past second level, but trying "Heal [[((@{class-0-level}-1) / 3)d6]]" isn't working - I need to find a way to get the output to always round up, so 5/3 rounds up to 2 instead of down to 1 for example (Fervor is 1d6 at 2, 2d6 at 5, 3d6 at 8, etc). Any advice is appreciated!

CheshirePhoenix said: I need to find a way to get the output to always round up I'm sure you'll be pleased to know that the ceil() function does exactly this! Heal: [[ [[ ceil((@{class-0-level} - 1) / 3) ]]d6 ]]"

So ceiling and floor round up and down? Thank you!
