Retrieves the imaginary part of a complex number.

Syntax

double cimag(   
   _Dcomplex z   
);  
float cimag(   
   _Fcomplex z   
);  // C++  
long double cimag(   
  _Lcomplex z   
);  // C++  
float cimagf(   
   _Fcomplex z   
);  
long double cimagl(   
   _Lcomplex z   
);  

Parameters

z
A complex number.

Return Value

The imaginary part of z.

Remarks

Because C++ allows overloading, you can call overloads of cimag that take _Fcomplex or _Lcomplex values, and return float or long double values. In a C program, cimag always takes a _Dcomplex value and returns a double value.
