Calculates the absolute value of a double precision floating-point value.
<math.h>
double fabs(double x);
x
Returns the absolute value of x. (A negative number is returned as
positive, a positive number is unchanged.)
No domain or range error will occur.
#include <math.h>
#include <stdio.h> /* for printf */
int main(void)
{
}
Output:
The absolute value of

Calculates the absolute value of a single precision floating-point value.
<math.h>
float fabsf(float x);
x
Returns the absolute value of x. (A negative number is returned as
positive, a positive number is unchanged.)
No domain or range error will occur.
