Function Documentation

template<class NT >

Extended_sign extended_sign

(

const NT &

nt

)

[inline]

Calculate the extened sign of a number.

For a regular number, the extened sign is teh same as the sign.

There is a specializated version for filtering included in CGAL/Polynomial/Tools/interval_arithmetic.h

Here is the call graph for this function:
