r min function does not return the correct number of decimals

In R I am using the min function on a vector of numeric values, like this vector: 

v <- c(16.22900, 16.28857, 16.47363, 16.47412, 16.00000, 16.49463, 16.27246, 16.0366, 16.49609)

However when I apply the min function, I get this return value

min(v)
[1] 16

instead I would like this result:

[1] 16.00000

I checked the class of the vector but all seems ok

class(v)
[1] "numeric"

Where is the problem?

You are caught between internal representation of a value and how it is displayed.

R> v <- c(16.22900, 16.28857, 16.47363, 16.47412, 16.00000, 
+         16.49463, 16.27246, 16.0366, 16.49609)
R> min(v)
[1] 16
R> sprintf("%10.8f", min(v))
[1] "16.00000000"
R> identical(min(v), 16.0000000000000000000)
[1] TRUE
R>
