I'm currently aware of round , ceil , floor functions available for macros from the Dice Reference wiki page . (In fact, I stumbled upon the undocumented round function before it was added to the wiki). Keep Drop also acts like a function for min/max types of operations. E.g. [[(3, 4)kl1]] = 3 Does anyone else know of any functions available to macros? I'm wondering if a table of them on the wiki would be helpful for new players to quickly see everything that is available.
