Obtains the imaginary part of a complex number #include <complex.h>
double cimag( double complex z );
float cimagf( float complex z );
long double cimagl( long double complex z );
A complex number is represented as two floatingpoint numbers, one quantifying the real part and one quantifying the imaginary part. The cimag( ) function returns the floatingpoint number that represents the imaginary part of the complex argument.
Example
double complex z = 4.5  6.7 * I;
printf( "The complex variable z is equal to %.2f %+.2f \xD7 I.\n",
creal(z), cimag(z) );
This code produces the following output:
The complex variable z is equal to 4.50 6.70 x I.
