My opinion: This is ludicrous. The end user is using a high level language and should not care whether the computer is digital or analog. For example, my calculator subtracts 0.4 just fine, and it is digital! I don't care about decimal points or any other excuses. THe fact is people expect languages on computers to work like their calculator does or like how grade school math worked.. simple, sensible. 1 minus 0.4 is 0.6. We need a Type to solve this problem if there isn't already one using currency or the suggested units. We are using high level languages here, not assembly code for creeps sake. Maybe currencies or the unit suggested by Florian solves the (IMO) ludicrous problem of todays languages. Imagine if we could not send emails because 'digital computers don't store text, they just store numbers, so you'll have to send your mail using numbers Sir'.
