You’re on the right track, but instead of convertting the value to a negative, divide it. and instead of using a function like math.round, use math.floor to properly represent the decimal.

local d = 10^(decimalPlace or 0);
return math.floor(number*d)/d;

but not a 15.0000000000002 ;

Not something you can avoid, as thats a precision issue in Lua.
