*where all microeuros convert to euros no matter what situation occures
Nope, the microeuros will never show up on my bank account, and I can't withdraw them. Anything less than a cent can't be cash, and even cents have been "rounded" to 5 cents minimum for years in my country.
then YOU may presume the microeuro to be a euro.. (emphasis on YOU)
It's more like I don't care about the microeuros, just like I don't care about the microsatoshis. For internal calculations it's okay, for practical purposes it's dust.
