cexp Function

Calculates the complex base- e exponential of a double precision complex value.

Attention: This function is implemented only by MPLAB XC32 C compilers.

Include

<complex.h>

Prototype

double complex cexp(double complex z);

Argument

z
value for which to return the complex base- e exponential

Return Value

Returns the complex base- e exponential of z.

Example

See the notes at the beginning of this chapter or section for information on using printf() or scanf() (and other functions reading and writing the stdin or stdout streams) in the example code.

#include <stdio.h>
#include <complex.h>

int main(void)
{
  double complex x, y;

  x = -2.0 + 1.0*I;
  y = cexp(x);
  printf("The complex base-e exponential  of %f + %fi is %f + %fi\n", creal(x), cimag(x), creal(y), cimag(y));
}

Example Output

The complex base-e exponential of -2.000000 + 1.000000i is 0.073122 + 0.113881i
