Big Number Help

I’m making a clicker game, so it would need to use very big numbers, and i found 1 tutorial on youtube, but it wasn’t really helping. I would like numbers that are not scientific and a script that can go from 999 to 1.00 thousand and so on. Can someone send a script of it? thanks.

I have a script for it, it manages large numbers, adding subtracting and displaying. LargeNumberClass | Integration | Unity Asset Store
