I did some more digging. At some point, NumericStepper calls NumberFormatter. I believe there is a bug in that logic because the NumberFormatter does not get created until you hit the up/down buttons.
Anyway, the NumberFormatter creates an instance of flash.globalization.NumberFormatter. On Windows, it has fractionalDigits=2 and trailingZeros=true, on Mac, it has fractionalDigits=3 and trailingZeros=false. The documentation says that default values are os-specific. So, IMO, this issue isn't just about setting fractionalDigits to 0 but also setting trailingZeros=false. The puzzling thing to me is that, NumberFormatter is based on GlobalizationBase which has a lot of code for being a non-display object that supports styles, but I don't see any code that propagates the default styles to the NumberFormatter. That's what seems wrong to me. If there was code at instantiation time that got the styles for every property on NumberFormatter, then folks should be able to set default styles in the defaults.css or elsewhere and have that affect formatting in their app. So, I think that's what should be fixed, and then the global selector should have trailingZeros=false and this problem would go away and we wouldn't have to tie the number of fractional digits to the stepSize.
