As others mentioned, it's because floating point numbers can't be 100% accurate with only 32 bits. There's an easy fix for it, though. Just drop an NSNumberFormatter onto both of your text fields, then choose to show two decimal places. Cocoa automatically rounds for you, and you'll get a nicely formatted two-digit number no matter what the input was. You can find the number formatter in the IB palettes.
