_Cbuild
, _FCbuild
, _LCbuild
Constructs a complex number from real and imaginary parts.
Syntax
_Dcomplex _Cbuild( double real, double imaginary );
_Fcomplex _FCbuild( float real, float imaginary );
_Lcomplex _LCbuild( long double real, long double imaginary );
Parameters
real
The real part of the complex number to construct.
imaginary
The imaginary part of the complex number to construct.
Return value
A _Dcomplex
, _Fcomplex
, or _Lcomplex
structure that represents the complex number (real
, imaginary
* i) for values of the specified floating-point type.
Remarks
The _Cbuild
, _FCbuild
, and _LCbuild
functions simplify creation of complex types. Use the creal
, crealf
, creall
and cimag
, cimagf
, cimagl
functions to retrieve the real and imaginary portions of the represented complex numbers.

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.
