cexp

double complex cexp(double complex z);

calculate the complex exponential

#include <stdio.h>
#include <complex.h>
 
int main( void )
{
 
   double complex z=4.2424 + I*(-2.41231);
   double result;
   result = cexp(z);
   printf("cexp(%f + (%f)*I) = %f + (%f)*I\n",creal(z), cimag(z),creal(result),cimag(result));
   return 0;
}

  cexp(4.242400 + (-2.412310)*I) = -51.878503 + (0.000000)*I
