Nice to see the English translation.<p>Here&#x27;s info about digital representation of binary numbers:<p>&gt;Since numbers are punched using the full 24 binary digits, they will be preserved for use in later computations. Otherwise the required translations back and forth would . . . soon drift out of integerness.<p>This is like a very early warning for floating point enthusiasts.

Offtopic: since I had no way to email a repost invite for <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38972831">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=38972831</a>, I made a fresh copy of it. I hope that&#x27;s ok!
