The intent is to indicate a difference in initiative bonuses, as the decimal, to break ties. For example, two characters roll initiative and both get a 10 P1 has an initiative bonus of 4, which is represented by adding 0.04 to that, for a result of 10.04. P2 has an initiative bonus of 6, which is represented by adding 0.06 to that, for a result of 10.06. The higher bonus will appear first in the turn order, a common rule in most games. How you're getting a 2.14, I'm unsure.
