Not Adding 0.1 Correctly

[Wildcutepenguin (Wild)]

This is super weird. I’ll give you a simple version of my script:

local count = 0
repeat
	count += 0.1
	print(count)
	task.wait(0.1)
until waiting == false

This should print out something like, 0.1, 0.2, 0.3 etc. but this is what’s printing out:

Floating point numbers

Solution might be to use round to a decimal place.

How to round to 2 Decimal places?

Multiply the value by 100 then use math.floor(value) then divide by 100 example local value = 0.984375 value *= 100 value = math.floor(value) value = value / 100

Script won't print out "What" for some reason

When dealing with decimals if you learnt computer science it’s a floating point number and the computer basically stores it as 0.40000009 from what I remember. Basically equality is unreliable when decimals come into play. Better to use > or < instead but there is also the method below which should work.

I came into the same problem it’s the lua interpreter the problem
