map_dbl() and map_int()

Some flavors of map_*() are very similar. map_dbl() and map_int() both output numbers. map_int() outputs integer vectors, which have numbers with no decimals. map_dbl() outputs double vectors, which have numbers that can have decimals. Take a closer look at how using different map_*() functions affect outputs.

Here is the map_*() table again as a reference.

`map_*()`	Output
`map_chr()`	character vector
`map_lgl()`	logical vector [TRUE or FALSE]
`map_int()`	integer vector
`map_dbl()`	double vector
