In computing, zero exists.

It doesn't, it's a placeholder.
What's the function of zero in computing?
Also how about positive and negative zero?
In the case of #Bitcoin, we're trending towards ~21M if we add decimal places.
If we don't add any, <~21M Bitcoins will have come into existence.
Henry Grady Weaver, [The Mainspring of Human Progress](https://a.co/d/gFiZHBB) talks about the invention of zero. Very interesting.
