Why are these numbers not equal?

Can anyone explain to me, why R answers FALSE in the following case?

(1-0.9)>=0.1

How can I get TRUE for comparisons of that kind?

Answer 1

You could create your own binary operators to do what you’re after and store them in your .Rprofile:

`%>=%` <- function(x, y) all.equal(x, y) | x > y
`%<=%` <- function(x, y) all.equal(x, y) | x < y

c(1-.9)>=.1
c(1-.9)%>=% .1
