Help reading big numbers

I need someone to translate what some of the really big numbers mean. For example, I (somehow) managed to deal "M994" damage in a single hit, but I have no idea what that number is supposed to mean. It also appears as though that number, regardless of "I" or "M" before it, acts just the same as "9999" in terms of damage, so my request may be mostly for useless information.

There's three things to keep in mind here:

• M is 10, I is 11, the green numbers are 16 + the number (so green 5 is 21), S is 26, the blue numbers are 27, 28, 29, and 30, and the cursor is 31.
• Every monster can have at most 30k HP per life, after which any extra damage is ignored. So doing 10k+10k+10k will result in the same thing as 14k+15k+31k.
• The damage will be much clearer in v9, whenever that comes out.

Awesome, thanks for clearing that up!
Really excited for v9, whenever that's coming out.
