  x,
  shorthand = NULL,
  na_values = c("", "NA"),
  dec = ".",
  bigmark = ","
)

x <- c("12", "34.567", "[c]", "NA", "56.78[e]", "78.9", "90.123[e]")
shrthnd_list(x)
#> <shrthnd_list[2]>
#> [c] (1 location): 3 
#> [e] (2 locations): 5, 7 

sh_x <- shrthnd_num(x)
sh_x
#> <shrthnd_num[7]>
#> [1] 12.00     34.57        NA [c]    NA     56.78 [e] 78.90     90.12 [e]
