Detailed Description

Provides an Eigen-like NumTraits struct for querying traits of a number type.

The bertini::NumTraits struct provides NumDigits and NumFuzzyDigits functions.

Function Documentation

Precision() [1/4]

unsigned bertini::Precision ( dbl_complex )

inline

Get the precision of a number.

For complex doubles, this is trivially 16.

Precision() [2/4]

void bertini::Precision ( dbl_complex , unsigned prec )

inline

For complex doubles, throw if the requested precision is not DoublePrecision.

Precision() [3/4]

unsigned bertini::Precision ( double )

inline

Get the precision of a number.

For doubles, this is trivially 16.

Precision() [4/4]

void bertini::Precision ( double , unsigned prec )

inline

For complex doubles, throw if the requested precision is not DoublePrecision.
