Other notation styles

I'm not sure about anyone else, but the current numbering shorthand loses me past "decillions". I feel it's already too easy to mix up s="sextillion" and S="septillion". I may be alone in this, but I keep trying to buy a septillion's qc worth of an investment and wondering why I didn't get it all when I have 100 sextillion qc or so, until I facepalm a second later because I failed to tell the difference between an upper and lower case 'S'. Also, other games have run into trouble with colliding shorthand making numbers like "1 ssx" ambiguous.

In that vein, I wonder how easy it would be to replicate the scientific/engineering/hybrid notation system from swarmsim (http://www.kongregate.com/games/swarmsim/swarm-simulator)?
