Compute the hyperbolic sine
#include <math.h>
double sinh( double x );
float sinhf( float x );
- x
- The angle, in radians, for which you want to compute the hyperbolic
sine.
libm
Use the -l m option to
qcc
to link against this library.
The sinh() and sinhf() functions compute the hyperbolic sine (specified in radians) of
x. A range error occurs if the magnitude of x
is too large.
The hyperbolic sine value.

If an error occurs, these functions return 0, but this is also a valid
mathematical result.
If you want to check for errors, set
errno
to 0, call the function, and then check errno again.
These functions don't change errno if no errors occurred. |
