TakeDamage overflowing at int32 limit although api reference says it's a float value?

Help and Feedback Scripting Support

What do I want to achieve?
I want to know a way to fix or bypass this “bug” that I run into (it could be intentional but I doubt it)

What is the issue?
I have a damage script. And whenever I set the damage past 2147483647 (32bit integer limit), it starts to overflow. However the api reference states that TakeDamage holds a float value. (which I believe can store much bigger numbers than 2147483647)

I have tried to do (insert humanoid here).Health = (insert humanoid here).Health - damage instead of using takedamage, however the Humanoid ends up taking 0 damage as supposed to taking -2147483648 damage

(this was Evercyan’s RPG Kit except edited to work on R15 instead of R6, uses alternatives to deprecated code and has a bit of anti-exploits I made myself.)

If I’m correct, float32 can store numbers up to 1^128

I think this is due to math.random() overflowing. Try this:

local dmg = Random.new():NextInteger(require(tool.WeaponConfig).MinDamage,require(tool.WeaponConfig).MaxDamage)

You were close! It almost worked. I tried NextNumber instead of NextInteger (since float64 stores way more than int64)

I’ll take it tho, it still helped me solve my problem
