In case you're all curious, the formula for how much your stat goes up when leveling is
((int)((nextLevel * growth * 167772) / 16777216) - (int)((currentLevel * growth * 167772) / 16777216))
For those of you who know nothing of programming, (int) means you only take the integer part before the decimal. To be precise though, it doesn't even need to be there because the data type is already integer.
If you're leveling up from 3 to 4, nextLevel would be 4 and currentLevel would be 3.
If a growth is, for example, 80%, the number in place of "growth" would just be 80.
