Should I be flooring before I put in these numbers for damage calculation?

Thanks everyone for the help so far. The main stat calculations are nearly perfect now. After quadruple checking my gear, skills, and character card effects, my DEX matches exactly and STR is off by only 4 points.

Lastly, I should add 1.5*level and 1.08*base HP to the formula in my original post, correct? Is there a way to determine base HP, even if it's just a rough estimate?
