Calculates the hyperbolic sine function of a double precision floating-point value.
Include
<math.h>
Prototype
long double sinhl(long double x);
Argument
x
Return Value
Returns the hyperbolic sine of x
.
Remarks
A range error will occur if the magnitude of x
is too
large.
Example
#include <math.h>
#include <stdio.h>
#include <errno.h>
int main(void)
{
long double x, y;
errno = 0;
x = -1.0F;
y = sinhl(x);
if (errno)
perror("Error");
printf("The hyperbolic sine of %Lf is %Lf\n", x, y);
errno = 0;
x = 0.0F;
y = sinhl(x);
if (errno)
perror("Error");
printf("The hyperbolic sine of %Lf is %Lf\n", x, y);
}
Example Output
The hyperbolic sine of -1.000000 is -1.175201
The hyperbolic sine of 0.000000 is 0.000000
