objects, and you will use "all.equal".

Dear R users,
I am using R version 2.0.1 (2004/11/15) on an i386-pc-mingw32 platform. I
encounter the following problem while using cumsum:
> a <- rep(0.01, 100)
> b <- cumsum(a)
> sum(a) == 1
[1] TRUE
> b[100] == 1
[1] FALSE
Am I missing something? Should cumsum have such an outcome?
Thanks in
