Compute the hyperbolic sine
#include <math.h> double sinh( double x ); float sinhf( float x ); long double asinhl( long double x );

Use the -l m option to qcc to link against this library.
These 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. |
#include <stdio.h> #include <math.h> #include <stdlib.h> int main( void ) { printf( "%f\n", sinh(.5) ); return( EXIT_SUCCESS ); }
produces the output:
0.521095
