How can I undo multiple exponents?
The more descriptive question is, How can I code it so that whenever I pickup an item it cuts my health in half, but I should be able to set it to any value and it should work?
I have an item I pickup that cuts my health in half. The only issue I currently I have is that I want it to be settable. For example lets say the player has 100 HP, I set their item to 2, their HP is now 25 as it is being cut in half 2 times.
I also want it to be decreased as well, lets say the player has 5 of this item, I can set it to 1 and it would be as if they only had 1 item.
Both of the features don't work with the code I'm using. Here is the code right now:
Before reading it, just know that the base health is the health of the humanoid. The last value is the value before it was picked up, and the child.Value is the value now. The thought behind it was that in the first parentheses I would undo the previous items, then after that I would set it as normal.
if name == 'SharpGlasses' then
--Cuts health in half
baseHealth.Value = (baseHealth.Value * 2 ^ lastValue) * 0.5 ^ child.Value
end
Here are the problems that come up from this code: If you pick up 4 of the item, not setting it, but one at a time, it sets your hp to 6. But if you set the item to 4, your hp gets set to 7. Here is the issue in the video below.
(You might have to copy and paste it as I was having issues just clicking on it)
If you set it instead your HP becomes 7. As in I go into the server viewer and then set the item value manually.
Another issue, if you drop the item your HP doesn't become the original value. Here is the video representing the issue:
As you can see after dropping the item the HP is now 112 instead of the starting 100. Also, I know for sure that this isn't the dropping function fault as all it does is subtract the drop amount from the current amount and sets it to the value.
Any help would be greatly appriecated!

hey there, it's going to be impossible to get perfect values because your health is being constantly rounded all over the place.
one thing I can say for certain about your second problem is that your extra health is happening due to a rounding error. what the player's health really should be is 6.25, but now it's 7. notice that 7 * 2^4 is 112.
to tell the truth, I am not completely certain why you are getting either 6 or 7 for your first issue, but that probably has something to do with a rounding error as well.
my suggestion is that perhaps you can try storing an extra value for the player's "true" health, in decimal form, which you use for all your calculations. then, whenever you set the player's health, simply round that value.
edit: another note, if you have more items that tamper with the players' health, unless this is intentional, simply doing reverse operations won't work. imagine if the player heals after taking damage, then you multiply their hp back with reverse calculations; it will be above what you intended. you might want to just make it simpler and set a hard multiplier against their maximum hp.
