Retrieves the value of a number raised to the specified power, where the base and exponent are complex numbers. This function has a branch cut for the exponent along the negative real axis.

Syntax

_Dcomplex cpow(   
   _Dcomplex x, _Dcomplex y   
);  
_Fcomplex cpow(   
   _Fcomplex x, _Fcomplex y   
);  // C++ only  
_Lcomplex cpow(   
   _Lcomplex x, _Lcomplex y   
);  // C++ only  
_Fcomplex cpowf(   
   _Fcomplex x, _Fcomplex y   
);  
_Lcomplex cpowl(   
   _Lcomplex x, _Lcomplex y   
);

Parameters

x
The base.

y
The exponent.

Return Value

The value of x raised to the power of y with a branch cut for x along the negative real axis.

Remarks

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

Requirements

Routine	C header	C++ header
`cpow`, `cpowf`, `cpowl`	<complex.h>	<ccomplex>
