[SOLVED] printf / sprintf issue with remove sign on numbers

Issue

I have a number that may be negative or positive and I want it to pop out of sprintf() without the negative or positive sign. How would I do it?

I tried %d % d %- d %+ d % -d % +d and none of them work.

I tried gcc 4.8.2 and g++ 4.8.2 and it does not work. Is this a bug in gcc?

Solution

There is no format string that applies a absolute value functionality.

Here is what you have to do:

#include <stdio.h>
#include <math.h>

void main()
{
  int num = -6000;
  printf("%d\n", abs(num));
}

• %d will render 34 as 34 and -34 as -34.
• % d will render 34 as (space) + 34 and -34 as -34.
• %+d will render 34 as +34 and -34 as -34.
• "%5d will render 34 as (three spaces) + 34 and -34 as (two spaces) + -34. They both will use the field size 5.
• "%-5d will render 34 as 34 + (three spaces) and -34 as -34 + (two spaces). They both will use the field size 5, but left justified because of -.
