printf, how to insert decimal point for integer

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 digits so the example numbers appear as

44.55, 3.12, 5.60 or 0.70

If there is no printf solution, is there another solution for this?

I do not wish to use floating point.

Solution

  • %.2d could add the extra padding zeros

    printf("%d.%.2d", n / 100, n % 100);

    For example, if n is 560, the output is: 5.60

    EDIT : I didn't notice it's UINT16 at first, according to @Eric Postpischil's comment, it's better to use:

    printf("%d.%.2d", (int) (x/100), (int) (x%100));
