how to round a vector consists of numbers,NA, and NaN

What is the best way to round a vector that consists of numbers, NA, and NaN. I don't want to omit the NA or NaN because I want to retain the order of the numbers.

x = c(2,3,4,NA,"NaN",3, 5)
round(x,2)  #does not work

  library(plyr)

 round_any(x,1)
  [1]   2   3   4  NA NaN   3   5

x is a character vector because it contains a character "NaN". Converting x to numeric will help.

x = c(2,3,4,NA,"NaN",3, 5)
class(x) # To see the class of x
round(as.numeric(x),2)

There should not be quotes around NaN. "NaN" is a character string; NaN is numeric. If this happens outside your toy example it suggests there is a problem elsewhere in your code. 

x = c(2,3,4,NA,NaN,3, 5)
round(x,2)  
# [1]   2   3   4  NA NaN   3   5
