Defined in header <complex.h>
float complex       cexpf( float complex z );		(since C99)
double complex      cexp( double complex z );		(since C99)
long double complex cexpl( long double complex z );		(since C99)

Computes the complex base-e exponential of z.

Parameters

z

-

complex argument

Return value

The base-e exponential of z.

Example

Run this code

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

Output:

-1.131204+2.471727i
