How is $2.9bn to $7k a 99% cut? It’s far closer to a 100% cut…

[–] Rhaedas@fedia.io 25 points 3 days ago

It's 99.99%, repeating, of course...

Because $7386 is a lot more than $0.

And a lot less than $29,000,000.

...huh? That would be 0%

A 99% reduction from $2.9 billion is $29 million. On the scale from $0 to $29 million, $7,386 is much closer to $0, so it’s more accurate to say the deal was cut by 100% unless you want to quote it with several decimal places.

It’s 99.9997% to 4 places.
