Maybe a simple problem with comparision

General
1 
a <- 0.3
b <- 0.3
c <- 0.3
(a+b+c) < 0.9

when i execute this code i get this " [1] TRUE"
and i cant see how is this true...bec 0.3+0.3+0.3 = 0.9 and 0.9 is not < 0.9, so the right answer should be false....

This has to do with floating point precision, read this FAQ for an explanation.
