C fabs Function

The C fabs function is a Math Function used to return the absolute positive number of a given value or a specified expression. The syntax of the fabs is

double fabs(double number);

C fabs Function Example

The math Function allows you to return the absolute positive number. In this math C fabs program, we will find the absolute positive number of different values and display the output.

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

int main()
{
    printf("\n The Absolute Value of 0       = %.4f ", fabs(0));
    printf("\n The Absolute Value of 1       = %.4f ", fabs(1));
    
    printf("\n The Absolute Value of 152     = %.4f ", fabs(152));
    printf("\n The Absolute Value of 400.36  = %.4f ", fabs(400.36));
    
    printf("\n The Absolute Value of -27.32  = %.4f ", fabs(-27.32));  
    printf("\n The Absolute Value of -90     = %.4f ", fabs(-90));
  
    return 0;
}

fabs Example 2

In this C Programming example, we allow users to enter their own values. Next, this program uses the fabs function to find the absolute positive number of the user-given value.

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

int main()
{
    float number, absValue;

    printf(" Please Enter any Numeric Value :  ");
    scanf("%f", &number);
  
    absValue = fabs(number);
  
    printf("\n The Absolute Value of %.2f = %.4f ", number, absValue);
  
    return 0;
}

 Please Enter any Numeric Value :  -23.456

 The Absolute Value of -23.46 = 23.4560
