_Cmulcc, _FCmulcc, _LCmulcc

Multiplies two complex numbers.

Syntax

_Dcomplex _Cmulcc( _Dcomplex x, _Dcomplex y );
_Fcomplex _FCmulcc( _Fcomplex x, _Fcomplex y );
_Lcomplex _LCmulcc( _Lcomplex x, _Lcomplex y );

Parameters

x
One of the complex operands to multiply.

y
The other complex operand to multiply.

Return value

A _Dcomplex, _Fcomplex, or _Lcomplex structure that represents the complex product of the complex numbers x and y.

Remarks

Because the built-in arithmetic operators don't work on the Microsoft implementation of the complex types, the _Cmulcc, _FCmulcc, and _LCmulcc functions simplify multiplication of complex types.

Requirements

Routine	C header	C++ header
_Cmulcc, _FCmulcc, _LCmulcc	<complex.h>	<complex.h>

These functions are Microsoft-specific. The types _Dcomplex, _Fcomplex, and _Lcomplex are Microsoft-specific equivalents to the unimplemented C99 native types double _Complex, float _Complex, and long double _Complex, respectively. For more compatibility information, see Compatibility.
