Retrieves the argument of a complex number, with a branch cut along the negative real axis.

double carg(   
   _Dcomplex z   
);  
float carg(   
   _Fcomplex z   
);  // C++ only  
long double carg(   
   _Lcomplex z   
);  // C++ only  
float cargf(   
   _Fcomplex z   
);  
long double cargl(   
   _Lcomplex z   
);  

Parameters

z
A complex number.

The argument (also known as the phase) of z. The result is in the interval [−π, +π].

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