I am Subracting two Double Variable numbers getting 0 as output But for Some other values I am getting output as like this -2.98023E-08 why it is happening

[ppr (Peter Preuss)]

internally computers will get a small fraction as a result.

have a look here and also for some solution approaches:

I have two values First one is 263926176.9 and Second One is 263926176.9 Both are same I am trying to subracting this Expecting output as 0 But I am getting this Value -2.98023E-08

Suggest a Correct way to get 0 in Output, Working in Excel
