Modulus acts kinda weird

1. What do you want to achieve? Keep it simple and clear!
   So my code is expected to work when modulus of current formula level and required one is more than -0.05(just in case of weird rounding sometimes). So let’s say formula Level is 6 and required is 5 and function seems to do weird stuff, like increasing exponent 2 times a row(when it shouldn’t), exponent should only increase when formula level % required level == 0

Code:

function CalculateExponent(formulaLevel, requiredLevel, perExpo)
	local exponent = 1
	
	if formulaLevel >= requiredLevel then
		
		while formulaLevel > 0 and math.round(formulaLevel) % requiredLevel >= -0.05 do
			print(formulaLevel, formulaLevel % requiredLevel)
			formulaLevel -= requiredLevel
			exponent *= perExpo
		end
	end
	
	return exponent
end

Also here is screenshot of what happens:

So as you can see on level 5 and level 6 exponent increase. Also on level 10 it not increase

but on level 11 it increase. Weird.
