[LUA Function] getLevelByExperience(cexp)

[Xagul]

Hello, I recently found myself in need of a function like this... after about an hour of tearing my hair out working with a friend trying to reverse the getExperienceForLevel function we finally figured it out!
This function will output the level of given experience. For example:

getLevelByExperience(4200)

returns 8


Without further delay, here is the belly of the beast:

function getLevelByExperience(cexp)
	return math.floor(math.pow((math.sqrt(3)*math.sqrt(243*math.pow(cexp, 2)-48600*cexp+3680000)+27*cexp-2700),1/3) / math.pow(30,2/3)-((5*math.pow(10,2/3)) / (math.pow(3,1/3)*math.pow((math.sqrt(3)*math.sqrt(243*math.pow(cexp,2)-48600*cexp+3680000)+27*cexp-2700),1/3)))+1)+1
end

I don't know if this will be useful to anyone... but its here now, waiting for that 1 person like me that happens to have a use for it!

it seems like the same, maybe the formula is different, but the result should be the same(I haven't tested)
