As many of you know, implementing initiative tie-breakers (e.g. 1d20+12.12 instead of 1d20+12) may cause issues in the form of getting trailing 99999999997 or something equally unhelpful in the number you roll. However, I've recently discovered a solution that seems to cover all cases and makes initiative tie-breakers robust. As such, people who are implementing initiative tie-breakers, or are considering to implement them, or were previously held back from implementing them by this dreaded bug, might be interested in incorporating the solution in their macros. The solution is simple: things like "1d20+12.12" have to be replaced with things like "1d20+12+0.12". This simple change resolved problems with tie-breakers in all tests that I've performed (that is, all initiative modifiers from 1 to 30). Additionally, putting the 1d20 before the other numbers is important .
