Detailed Description

Provides bertini extensions to the double and complex<double> types.

Function Documentation

isnan()

bool bertini::isnan ( std::complex< double > const & z )

inline

an overload of isnan, for std::complex<double>

operator*()

std::complex< double > bertini::operator* ( unsigned i, std::complex< double > z )

inline

Overload * for unsigned * complex<double>

pow()

dbl bertini::pow ( const dbl & z, int power )

inline

Compute +,- integral powers of a std::complex<double> number.

This function recursively calls itself if the power is negative, by computing the power on the inverse.

Note

This overload was removed from C++ in C++11, for some insane reason. Here it is, back in black.

RandReal()

double bertini::RandReal ( )

inline

Gets you a random real number between -1 and 1, fwiw.
