Surface Mounted Resistor Codes

I work the the best people in the world. I was trying to figure out these numeric resistor codes, and my coworker Laura immediately pointed me here here.  Here's an example from that page:

First two digits: two digits in the value.
Third digit: number of zeros after the first to digits.

334 = [33][0000] = 330k ohms
440 = [44][] = 44 ohms (not 440, the zero means zero zeros!)
000 = link (no resistance)
