Stuf HP/MP Format

[Kendian]

Would there be any way, or could someone point me in the direction to have a shortened number format in Stuf? In example I'd like 135.5k to read as either 135k5 or just plain 135k, rounding up or down, as the case may be.Although, in my opinion, rounding down would be the way to go, lol. Better to think you have less than you do, than more.
I wouldn't mind using a lua script to accomplish this, if possible. Any and all help is, of course greatly appreciated. Thanks, all~
