Retrieves the absolute value of a complex number.

double cabs(   
   _Dcomplex z   
);  
float cabs(   
   _Fcomplex z   
);  // C++ only  
long double cabs(   
   _Lcomplex z   
);  // C++ only  
float cabsf(   
   _Fcomplex z   
);  
long double cabsl(   
   _Lcomplex z   
);  

Parameters

z
A complex number.

The absolute value of z.

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