c언어 절대값 구하기 abs()

![](https://cdn.steemitimages.com/DQmdQmXukxicyaK5978LBB3rYq9RLYEJ7axRRFtjdwKJ1s1/image.png)

안녕하세요!! @wonnieyoon 입니다.
코딩을 하다보면 생각보다 절대값을 사용해야 하는 경우가 많습니다.
특히, 저의 경우 절대값을 주로 HTS 개발중 현재가를 가져와서 
데이터를 가공할때 사용합니다.
현재가 : -9999, +5000 이런식으로 오는데 -,+ 붙는 이유는 부호를 나타내기 위해서 내려옵니다.
현재가에 대해 이해가 안된다면 주식을 한번 해보는것을 추천!!

※ abs()
:절대값을 만들어주는 함수

※사용법
#include "stdafx.h"
#include <math.h>

int _tmain(int argc, _TCHAR* argv[])
{
	int a = -3;
	printf("%d\n", abs(a));
	
}

※결과
3
