printf, how to insert decimal point for integer

Question

I have an UINT16 unsigned integer of say

4455, 312, 560 or 70.

How to use printf to insert a decimal point before the last two

Answer 1

You can use printf directly with out using float

printf("%d.%02d", num/100, num%100);

%02d means right align with zero padding.

if num is 4455 ==>output is 44.55  
if num is 203  ==>output is 2.03

EDIT:
by seeing comment from @ Eric Postpischil , it's better to use like this.

printf("%d.%02d", (int) (num/100), (int) (num%100));
