Not if he wants to convert a float to an int (check my quote from the perlfunc document). I forgot to include a table of results. Here it is:

$ ./chksprintf.pl
147    14700    14700    14700
147.1  14710    14710    14710
147.2  14720    14720    14719
147.3  14730    14730    14730
147.4  14740    14740    14740
