Units

Here is the way that the game depicts different numbers and what their official names are. Each representative character is comprised of 1000 of the previous, or 1000 times greater.

Scientific notation is used to show very large numbers in a compact space. 1470000000 turns into "1.47e9", where "eX" is 10^X. The number X also represents the number of times the decimal places is moved to the right in the notation.

Trivia

• "n!" in normal mathematics represents n factorial, which is n*(n-1)*(n-2)...*2*1. Therefore 1000! would become 1000*999*998...*2*1 ≈ 4.02e2567, much more than the value of "1000!" in-game. In comparison, there are roughly only 1e80 particles in the universe!
• "%" divides a number by 100 in mathematics whereas the in-game version multiplies it by 1e54.
