Lets say I use this code: p.leaderstats.Money.Value = 200.1 it should set the players money to 200.1, correct? Now the leaderboard will indeed say 200.1, however if the money has something subtracted from it, or if I go into the player, and check the value myself, it will equal 200.09999999999999. Does anyone know why? The leaderboard code does not do anything to the value of it.

NumberValue going down by something like 0.0000000001?

Floating-point errors. In exchange for a larger range of numbers, computers sacrifice the ability to represent a large amount of numbers exactly (especially decimals). This can have issues when checking for equality, but this can be resolved by factoring in a very small number, often called Epsilon.
ROBLOX uses doubles, so can represent integer numbers exactly up to something like +/- 1000000000000000 (according to a simple test that I ran)

So is there a way for me to actually make it 200.1, as adding something to it is very odd.
There is no way. 200.1 cannot be represented in floating-point format. It will probably not affect you, anyway.
