Well basically my numbervalue value is 682414565312878483175636992 if I try to add one so it becomes 682414565312878483175636993 it just turns back to the old number on the other side if I change it to bacome 782414565312878483175636992 or change the sixth number it works perfectly 682415565312878483175636992
Switch to a StringValue. Lets you use larger numbers and should fix that bug you’re having.

Still does the same thing even though I used a string value.
Show me what you are doing exactly.
you can try it for yourself, make a numbervalue make 1 Button that gives 1SP of the currency, click it a couple times, then click another button which gives a low amount like 1 for example, the amount won’t be changing, it will just keep reverting back to the big number unless you click the 1SP button again
Pretty sure its a roblox bug at this point
It’s not a bug per se, it is the way floating point numbers work, see: Double-precision floating-point format - Wikipedia
Precision goes down the further away you go from 0 and the largest Integer you can safely store in lua is 2^53 or 9,007,199,254,740,992, anything larger than and you don’t have enough precision to store every Integer accurately anymore.
See:
print(2^53-1-2^53 == 0) --this will print false
print(2^53+1-2^53 == 0) --this will print true

And is there a way to get over that
Not easily if you want to do math with it and you shouldn’t even need that much precision to begin with.

You’re right, okay thanks for the information I’m not that good at math 
, I was just wondering.
