[R] Strange Bug in R

[Neverstop]

Hi all.
I don't understand why R works this way:
> rm(list=ls())
> require(foreign)
> dataset <- read.dta("http://www.ats.ucla.edu/stat/data/ologit.dta")
> min(dataset$gpa)
[1] 1.9
> min(dataset$gpa)>=1.90
[1] FALSE
> min(dataset$gpa)>=1.9
[1] FALSE
> min(dataset$gpa)>1.89
[1] TRUE
Shouldn't I get 3 TRUEs?
Am I missing something?
Thank you.
