I'm in the process of doing so now
Computers are binary, yeah? So we have to represent fractional numbers with binary, too.
In decimal, numbers past the decimal point are 10^-1, 10^-2, ... etc. In binary, they're 2^-1, 2^-2, ....
2^-1 is one half, so 0.1 in binary is 0.5 in decimal. 2^-2 is one quarter. 0.11 in binary is 0.75 in decimal. And of course you've got 0.01 = 0.25
The problem comes when representing decimal numbers that don't have neat binary representations. For instance, 0.1 in decimal is actually a repeating binary number: 0.0001100110011...
Fun fact: NaN is of type number
Well yes. But that's not why they're trying to impeach him.
Good lord that fucker is huge
You're adding a bunch of zeroes. Zero is the additive identity. It doesn't change the value.
Why not? How does that change the value?
Infinities do have different sizes, yes. But not on that scale. Both of these are countably infinite sets.
Think about this: there are infinitely many primes. Obviously, not every number is prime. But you can still map primes 1:1 with the natural numbers. They're both the same size of infinity.
That's not how infinity works
The non-pointy sides are also sloped. https://en.m.wikipedia.org/wiki/Shogi#/media/File%3AShogi_Koma_Ryoko.jpg
