This is a list of all the numbers that currently exist, though more may be invented later.
...but don't COUNT on it!
Calculable numbers
The numbers -1, 0, 1, and 2 are currently the only numbers to be fully confirmed. All numbers above 2 are theoretical and math does not work with them.
Fractional numbers
There exists a special value 1/12 which lies between 0 and 1. It is a very mysterious value, and little is known about it.
Unfractional numbers
Annoying numbers like π and e which don't have repeating digits. Unfortunately, most numbers are like this.
Theoretical numbers
These numbers are purely theoretical and are likely not to exist. See the page 3 for more information.

Years
The system of numbers for counting years is often considered separate from the main number system[citation needed], and are given their own section of the numbers.
Post-year numbers
Years will end before the year 2763;[citation needed] some speculate that time itself will end, while others say that we will simply switch to an alphanumeric system of counting years. Some theorize that the Roman Empire will return from their lunch break and bring back using Roman numerals for counting years.

idk what happened here
Long numbers
Numbers with more than four digits are considered to in a separate class from all other numbers. They're so far from the realm of practicality that at this point you're just putting symbols next to each other.
Long numbers
These numbers are above the integer limit and must be represented with a long data type.
Longer numbers
These numbers are too long to be long numbers.
Okay
What's the big idea
