I have a strange behaviour in R, looks like type conversions are messed up.

To reproduce:

expected:

typeof(3)

[1] "double"

as.integer(3)

[1] 3

!!!! strange:

typeof((0.3/0.1))

[1] "double"

as.integer((0.3/0.1))

[1] 2

also for trunc:

trunc(c(5,7))
c(0.5,0.7)/c(0.1,0.1)

and now watch the amazing!!!!:

trunc((c(0.5,0.7)/c(0.1,0.1)))
