Equation 2 · Part 9 · The EV Formula Is an Exact Production Function Trainers Solved by Accident

Denominator: 100

HP=⌊(2B+I+⌊E/4⌋)⋅L100⌋+L+10\text{HP} = \left\lfloor (2B+I+\lfloor E/4 \rfloor) \cdot \frac{L}{100} \right\rfloor + L + 10

What this part means

The complete quantity below the fraction bar; it must be nonzero for this division.

Its job in the formula

100 occurs below the fraction bar. The quantity above the bar is divided by this expression; zero is excluded as a denominator.

The passage around this formula

HP uses the same inner term but a different outer shell, adding the Pokémon’s level plus ten instead of multiplying by a nature: HP=⌊(2B+I+⌊E/4⌋)⋅L100⌋+L+10\text{HP} = \left\lfloor (2B+I+\lfloor E/4 \rfloor) \cdot \frac{L}{100} \right\rfloor + L + 10. At level 100 — the level Smogon’s singles tiers, including the OU tier this article draws its spreads from, are actually played at — the level term collapses to a clean multiplication by one, so every floor operation inside the level scaling vanishes and the formula reduces to simple integer arithmetic: raw…
