Is changing the floating combat numbers format possible?

[catacode]

Hi, I have been searching the net for an addon that would let me change the format of floating damage/healing numbers. For example from a number 2403453 to 2.4M. I havent been able to find such an addon, apart from MSBT which also replaces the way in which those numbers are shown on the screen. I have a bit of programing knowledge myself (mainly c++ and c) but i do not have much experience with lua or the blizzards api, so i am wondering, before i start learning lua, if it even possible to write such an addon, which would replace the format (not the font) of the numbers but keep the animations blizz like?
