cimag Function

Calculates the imaginary part of a double precision complex value.

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

Include

<complex.h>

Prototype

double complex cimag(double complex z);

Argument

`z`	value for which to return the imaginary part

Return Value

Returns the imaginary part of the double precision complex value 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;

  x = -2.0 + 1.0*I;
  printf("The imaginary part of %f + %fi is %f\n", creal(x), cimag(x), cimag(x));
}

Example Output

The imaginary part of -2.000000 + 1.000000i is 1.000000
