Dear All, I am running a r code on 32bit win, involving absolutely small numbers. Although I tried sth like the ratio of numers like 10^(-100) and did not have issue to get the correct answer, but still a little concerned about it. Could anyone give some suggestion or have any experience? Best wishes, Jie [[alternative HTML version deleted]]

Hello, I fear its a stupid question,..but here it is: If I do this simple calculation with the R console, I surprisingly do not get a zero. Why? -1.1-0.1+1.2 [1] -2.220446e-16 greetings, Ole -- View this message in context: http://r.789695.n4.nabble.com/1-1-0-1-1-2-is-NOT-null-Why-tp4636053.html Sent from the R help mailing list archive at Nabble.com.
