As numbers are growing quickly (exponentially) in this game, you will sooner or later be faced with numbers that look like this:

Big numbers will be displayed as a number followed by some letters. Obviously the letters serve as a way of describing the magnitudes. Otherwise your whole screen will be filled with numbers at some point.

You might be familiar with abbreviations like '1k' which stands for 1,000 (one thousand) but not know, what '1D' or '1a' means.
Luckily understanding all the symbols of the number notations is not as difficult as one might think.

>> A table containing all the symbols can be found in a separate section below. <<

The game lets you choose between different notation systems in the gameplay options menu. The 'Default' notation might confuse you more like others. I personally prefer 'Alternative':


All the different systems together with their advantages and disadvantages are explained below.

The default notation starts with abbreviations most people will recognize:

1.00 k = one thousand (kilo)
1.00 m = one million
1.00 b = one billion
1.00 t = one trillion

After that, if it reaches the next magnitude which is a quadrillion (1,000,000,000,000,000), the notation system switches to an alphabetical one, beginning with 'a'. After every power of thousand, small and capital letters alternate while progressing through the whole alphabet. But the letters B,K,M,T and L will be skipped as they are already used for the first four powers (and the small L can be confused with the capital i).

So the complete sequence of magnitudes is:
k, m, b, t, a, A, c, C, d, D, e, E, f, F, g, G, h, H, i, I, j, J, n, N, o, O, p, P, q, Q, r, R, s, S, u, U, v, V, w, W, x, X, y, Y, z, Z

Advantages:
+ you don't have to know the name of magnitudes bigger than trillions
+ the farther you progress into the alphabet, the larger the numbers are (usually)

Disadvantages:
- inconsistent system as it switches from English names to the alphabet
- confusion possible about the letters k, m, b and t
- notations not used in the real world
- difficult to work out the exact power of a number

The alternative notation system is more consistent than the default one. It only makes use of the English names for the powers of the numbers:

1.00 K = Thousand (kilo)
1.00 M = Million
1.00 B = Billion
1.00 T = Trillion
1.00 Qa = Quadrillion
1.00 Qu = Quintillion
1.00 Sx = Sextillion
and so on... (see table below)

If you are familiar with the names of magnitudes, this system might suit you better.
Nevertheless, confusion can happen if your native language is not English. Many other languages are using a name convention with powers of millions, while English is thinking in powers of thousands. For example an English 'billion' is a thousand 'millions' while in other languages a 'billion' is a million 'millions'. A thousand 'millions' is called a 'milliard' in these languages (see table below).

The sequence of magnitudes is:
K, M, B, T, Qa, Qi, Sx, Sp, Oc, No, Dc, Ud, Dd, Td, Qad, Qid, Sxd, Spd, Od, Nd, V, Uv, Dv, Tv, Qav, Qiv, Sxv, Spv, Ov, Nv, ...

Advantages:
+ consistent system
+ easy to understand
+ real number system

Disadvantages:
- you have to know the name of magnitudes to understand the system
- confusion possible between different languages

The scientific notation is widely used among different technical and scientific systems.
A large number will be presented with an 'e' followed by another number.

An easy way of understanding this symbol is:

For Example:
1 e3 = a one and 3 zeros = 1,000 (a thousand)
1 e7 = a one and 7 zeros = 10,000,000 (ten millions)

Mathematically speaking the eX part is just an abbreviation for a multiplication by 10 to the power of X (The letter 'e' stands for exponent):
1 e3 = 1 * 10^3 = 1 * 1000 = 1000

---

Advantages:
+ widely used number system
+ consistent system
+ useful even for very large magnitudes

Disadvantages:
- could be difficult to keep track of as symbols change quickly
- can be confusing for people without mathematical background

The engineering notation is almost the same as the scientific one. The only difference is that the exponent can only be a multiple of 3 which directly translates to the name of a magnitude (like million, billion, trillion, ...).

For example a comparison of the number 20,000,000 in these two notations:
Scientific: 2 e7 = 2 "ten millions"
Engineering: 20 e6 = 20 "millions"

---

Advantages:
+ real number system
+ consistent system
+ a symbol always directly translates to the name of a magnitude
+ useful even for very large magnitudes

Disadvantages:
- can be confusing for people without mathematical background

The leaf notation is exactly the same as the engineering one. The letter 'e' just gets replaced by the word 'Leaf' for fun.

1 Leaf3 = 1000

---

Advantages:
+ consistent system
+ a symbol always directly translates to the name of a magnitude
+ useful even for very large magnitudes

Disadvantages:
- can be confusing for people without mathematical background
- the length of the word 'Leaf' can make numbers look more confusing

This goes on for a long time...

When numbers are reaching the sky, even these notation systems will max out at some point.

The 'Default' system gets to its limit at 999.99 Z which is a number consisting of a total of 141 nines.
After that it switches to the 'Scientific' notation.

In theory the scientific number notation could go on forever, although one would run into the same problem of confusion if the numbers following the 'e' get too large.
The current maximum (for technical reasons) seems to be e308.

Following that, the absolute maximum number that will be displayed anywhere in the game is:

The maximums of the notation systems might be subject to change in further updates. I will try to update this guide. But please feel free to leave a comment if I missed something, you think this guide was helpful or you have other thoughts!
