2/10
Please, do not use infinity as a number, it annoys me when people use it so freely.
Just think to yourself, light travels at 3x10^8 m/s (rounded up), infinity is bigger than this.
The numbers eternal density just used, its bigger than that.
Also, in the terms you are using it as, its a number, however it is not. Simply it measns something which is infinite, that has no end, so in short you are saying that it is relating to numbers, and since the definition of infinity is something which has no end, you are saying nth/10 where nth is any number, including minus'
