[Solved] i % 1 does not give 0 in script, but manually in command line it does?

I have a piece of code that counts in a for loop but while counting I want it so whenever it is divisible by 1 to run a function. However, it keeps failing the 'checking if divisible by 1' part (it gives a different number). I just can't figure it out, unless it's some bug.

Here's a slightly edited copy of my script:

for i = 0,Time, 0.1 do
	Charge = i / Time
	if i % 1 == 0 then
		print(i, true,  i % 1)
		Function()
	else
		print(i, false, i % 1)
	end
	if HoldingZ == false then
		break
	end
	wait(.1)
end

And here's the output:

>   0 true 0
>   0.1 false 0.1
>   0.2 false 0.2
>   0.3 false 0.3
>   0.4 false 0.4
>   0.5 false 0.5
>   0.6 false 0.6
>   0.7 false 0.7
>   0.8 false 0.8
>   0.9 false 0.9
>   1 false 1 -- Why does it not output 0?
>   1.1 false 0.1
>   1.2 false 0.2
>   1.3 false 0.3
>   1.4 false 0.4
>   1.5 false 0.5
>   1.6 false 0.6
>   1.7 false 0.7
>   1.8 false 0.8
>   1.9 false 0.9
>   2 false 4.4408920985006e-16 -- Why does it not output 0?
>   2.1 false 0.1
>   2.2 false 0.2
>   2.3 false 0.3
>   2.4 false 0.4
>   2.5 false 0.5
>   2.6 false 0.6
>   2.7 false 0.7
>   2.8 false 0.8
>   2.9 false 0.9
>   3 false 1.3322676295502e-15 -- Why does it not output 0?
>   3.1 false 0.1
>   3.2 false 0.2
>   3.3 false 0.3
>   3.4 false 0.4
>   3.5 false 0.5
>   3.6 false 0.6
>   3.7 false 0.7
>   3.8 false 0.8
>   3.9 false 0.9
>   4 false 1.7763568394003e-15 -- Why does it not output 0?
>   4.1 false 0.1
>   4.2 false 0.2
>   4.3 false 0.3
>   4.4 false 0.4
>   4.5 false 0.5
>   4.6 false 0.6
>   4.7 false 0.7
>   4.8 false 0.8
>   4.9 false 0.9
>   5 false 1 -- Why does it not output 0?

Now here's what happens if I do this in the command line at the bottom of Roblox Studio:

print(5%1) -- Output: 0

What am I doing wrong? I am absolutely confused!

Thanks for helping!

I have no idea what this is happening. Fortunately, I was browsing around, and I found a replacement for the modulus (you aren't the only one having an issue with this operator):

a % b = a - math.floor(a / b) * b

It's not ideal, but hey! At least it returns the remainder. So, you could make a variable with this and write your code something like this:

local remainder = i - math.floor(i / 1) * 1

Hope this helped!

Use math.fmod, it does exactly what you want.

for i = 0,Time, 0.1 do
    Charge = i / Time
    if math.fmod(i,1) == 0 then
        print(i, true,  math.fmod(i, 1))
        Function()
    else
        print(i, false, math.fmod(i, 1))
    end
    if HoldingZ == false then
        break
    end
    wait(.1)
end
