Name
cimag
Synopsis
Obtains the imaginary part of a complex number
#include <complex.h> doublecimag
( double complex z ); floatcimagf
( float complex z ); long doublecimagl
( long double complex z );
A complex number is represented as two floating-point numbers,
one quantifying the real part and one quantifying the imaginary
part. The cimag()
function
returns the floating-point 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 × I.
