Those are all the same number. You aren't asking about the answer, you
are asking about how to control how the number is printed.

R tries to be consistent when it prints a vector, so you could convert
all the entries at once. For example,

[1] "12.0" "12.1"
If you want individual control on each entry, see formatC or sprintf.
Christos gave you the formatC version; the sprintf version is

[1] "12.0"
