Example:
Calculates the trigonometric arc sine function of a double precision
floating-point value.
<math.h>
double asin (double x);
x
Returns the arc sine in radians in the range of -pi/2 to +pi/2 (inclusive).
A domain error occurs if x is less than -1 or greater than 1.
#include <math.h>
#include <stdio.h> /* for printf, perror */
#include <errno.h> /* for errno
int main(void)
{
}
Output:
Error: domain error
The arcsine of 2.000000 is nan
The arcsine of 0.000000 is 0.000000
Calculates the trigonometric arc sine function of a single precision float-
ing-point value.
<math.h>
float asinf (float x);
x
Returns the arc sine in radians in the range of -pi/2 to +pi/2 (inclusive).
A domain error occurs if x is less than -1 or greater than 1.
#include <math.h>
#include <stdio.h> /* for printf, perror */
#include <errno.h> /* for errno
int main(void)
{
double x, y;
errno = 0;
x = 2.0;
y = asin (x);
if (errno)
printf("The arcsine of %f is %f\n\n", x, y);
errno = 0;
x = 0.0;
y = asin (x);
if (errno)
printf("The arcsine of %f is %f\n\n", x, y);
float x, y;
perror("Error");
