Retrieves the squared magnitude of a complex number.

Syntax

double norm(   
   _Dcomplex z   
);  
float norm(   
   _Fcomplex z   
);  // C++ only  
long double norm(   
  _Lcomplex z   
);  // C++ only  
float normf(   
   _Fcomplex z   
);  
long double norml(   
   _Lcomplex z   
);

Parameters

z
A complex number.

Return Value

The squared magnitude of z.

Remarks

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

Requirements

Routine	C header	C++ header
`norm`, `normf`, `norml`	<complex.h>	<ccomplex>
