Dear List,
I ran into some trouble by calculating differences. For me it is
important that differences are either 0 or not.
So I don't understand the outcome of this calculation
865.56-(782.86+0+63.85+18.85+0)
[1] -1.136868e-13
I run R version 2.71 on WinXP
I could solve my problem by using

but I would like to know the reason.
Maybe someone can help me?
