Defined in header <complex.h>
float complex       casinhf( float complex z );		(since C99)
double complex      casinh( double complex z );		(since C99)
long double complex casinhl( long double complex z );		(since C99)

Computes the complex arc hyperbolic sine of z with branch cuts outside the interval [−i; +i] along the imaginary axis.

Parameters

z

-

complex argument

Return value

The complex arc hyperbolic sine of z in the interval (−∞; +∞) along the real axis and in the interval [−iπ/2; +iπ/2] along the imaginary axis.

Example

Run this code

#include <stdio.h>
#include <complex.h>
 
int main(void)
{
    double complex z;
 
    z = csinh(1.0+2.0*I);
    printf("csinh(1.0+2.0*I)             ==> %f%+fi\n", creal(z),cimag(z));
 
    z = casinh(-0.489056+1.403119*I);
    printf("casinh(-0.489056+1.403119*I) ==> %f%+fi\n", creal(z),cimag(z));
 
    return 0;
}

Output:

csinh(1.0+2.0*I)              ==> -0.489056+1.403119i
casinh(-0.489056+1.403119i*I) ==> -1.000000+1.141593i
