How can I use a long double complex?

[tgel76]

Hi,
How can I declare a variable as lon double complex?
I want to use powl()and sqrtl() functions with complex number that I have calculate before and they are very big...

thanks

class complex
{
double r;
double y;
public:
complex& operator*=(complex x)
{
r*=x.r;
r-=y*x.y;
y=y*x.r+x.y*r;
return *this;
}
....
};

You may also use complex class (include the complex.h file) that comes with the standard C++ library (Borland). It even has support for mathematical functions like log, exp, pow, sqrt etc. Ankan.

Please do correct me if I am wrong. s-)
