Number compression, can I specify unsigned/numbersize?

[polill00]

I’m working with something that needs to store many numbers. And after some research it seems roblox’s numbers stores 64 bits in memory. When none of my numbers will be decimals, negative, or need to be above 8bits total. If I can somehow specify this I can save ~80% of memory, allowing for much higher limits.

It appears vector2 and vector3 have 16bit counterparts, but I can’t seem to find a way to specify any sort of compression for a single number.

Is there anyway I can do this?

Have to tried storing the information in a byte?
I am asking as that is 8 bits so meets your needs.

Making use of bytes

To put it simply, how does/can one make use of bytes in lua? More specifically: lua strings contain characters that are supposedly 1 byte each, meaning that a string of length 4 would make use of 4 bytes total for the characters of said string. Thus, we could utilize string.char(0 -> 255) to account for bytes 0000000 through 11111111. That being said, I have found things stating that the CONTROL characters are mostly all 6 bytes, and some other characters take up 2 bytes. My question then beco…

If your trying to save data into the datastore then this video will help

But if your trying to reduce ram usage

Then you can use bitwise operations to save multiple values into 1 variable

bit32 | Roblox Creator Documentation

-- the 2 numbers we want to save
local value1 = 123
local value2 = 46346

-- save both numbers into a single variable (double)
local save = bit32.replace(value1, value2, 16, 16)

-- extract the 2 values back from the single variable (double)
local loadedValue1 = bit32.extract(save, 0, 16)
local loadedValue2 = bit32.extract(save, 16, 16)

-- print the 2 values
print(loadedValue1)
print(loadedValue2)
