	experience.Value = experience.Value + ((maxexperience * 0.1)+ 3)
	print("experience : " .. experience.Value)
	
	if experience.Value >= maxexperience then
		print(experience.Value .. " is higher than or equal to " .. maxexperience)

Namaste it is i, dual

Normally I would write a really in-depth answer to any question I answer, but this one requires less depth so I'll keep it short.

There are 2 basic methods to do this in the math library

(https://developer.roblox.com/en-us/api-reference/lua-docs/math)

These are math.floor() and math.ceil().

math.floor() cuts off the decimal, and return the CURRENT integer

math.floor(4.1)) -> 4
math.floor(3.8)`) -> 3

Whereas math.ceil() cuts off the decimal, and returns the NEXT integer

math.floor(4.1)) -> 5
math.floor(3.8)) -> 4

Of course, if neither of these suits your tastes, you can always create your own rounding function, however I believe math.floor() is what you're looking for.

You can read more on Lua's math library here: http://lua-users.org/wiki/MathLibraryTutorial

That is all

adding to this you can use strings to get a more flexible result. so it would be something like this: tonumber(string.format("%.4f", "5.509453"))

math.floor(number)

will return the lower value of the number, so if number is 5.9, it will be 5.

math.ceil(number)

will return the higher value of the number, so if the number is 5.1, it will be 6.
