complex number overload

Suppose we have a complex number class and we overload the conversion
to double to return the real part. We also overload operator* to do
complex multiplication. Consider now:

complex a(...);
complex b(...);

complex c = a*b;

But the compiler complains ambiguity since it doesn't know whether to
do complex*complex , or convert to double first and do double*double.
Other than explicit casting is there a nice solution?

Don't overload the conversion to double, use a.real() and a.imag()
instead. With no conversion to double the compiler only has one
option: complex * complex.

I've been working on creating a Complex class for my own learning purpose (learn through doing etc.). I'm once again puzzled about something. I can't figure out how to overload the assignment operator. Here's what I'm trying to do. I've defined class Complex as class Complex { friend ostream &operator<<( ostream &, Complex & ); public: Complex( float = 0.0, float = 0.0 );

I'd like to get output formatting for my own classes that mimics the built-in output formatting. For example, >>> x = 4.54 >>> print "%4.2f" % x 4.54 In other words, if I substitute a class instance for "x" above, I'd like to make the format string apply to an element or elements of the instance. Can I somehow overload the "%" operator for that? Thanks.

Hi! I have a piece of code (shown below) involving complex numbers. The code is not running and giving error ("Invalid floating point operation" and "SQRT:Domain error"). I would be very thankful if someone can tell me where is the problem. I am aware that my code is far from being efficient and organized, and also there are many extra #include statements not really required for the code. I am a novice programmer, as you can see ! At...

Hello, I'd like to understand why the following code does not compile. It looks like a strangeness in connection with overload resolution for the <complex> header: The conversion operator double() of class B is called for the member complex::operator*=(double) as expected, but not for operator*(complex, double). The effect is, that the template matching (or overload resolution)

Complex Complex::operator+( const Complex &operand2 ) const { return Complex( real + operand2.real, imaginary + operand2.imaginary ); } this is my addition operator for 2 complex numbers. e.g. C1(3.2, 1.5) C2(2.1, 4.6) C1+C2 = (5.3, 6.1) How can i overload the operator+ to make an addition between a double and a complex number? for example 3.0 + C1 = (6.2, 1.5) Thanks.

Hi, In FFTW (http://www.fftw.org/), it defines the funciton fftw_malloc to allocate memory properly aligned. However, I only want to use new to allocate memory for std::complex<double>. Can some body show me how to redefine the new operator for an class already defined in the library? Thanks,

Suppose you have a complex number class, and you overload conversions to double by only taking the real part. You also overload operator* to do complex multiplication. You then write: complex a(...); complex b(...); complex c = a*b;

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
