Using that exact file you included? If so, then I suspect you are
confusing display and storage, though even then my default session
doesn't show integers.

How do you know that it is returning only integers? What is
options()$digits set to?

> myfile
  V1        V2       V3
1  1 50.790643 6.063498
2  2 50.790738 6.063471
3  3 50.791081 6.063380
4  4 50.791189 6.063552

[1] "50.7906430000"
