Member Function Documentation

template<typename C >

void atlas::polynomials::Safe_Poly< C >::safeAdd	(	const Safe_Poly< C > &	q,
		Degree	d,
		C	c
	)

Adds x^d.c.q, to *this, watching for overflow, assuming |c>0|.

NOTE: may forward a NumericOverflow exception.

NOTE: we need to be careful in the case where q = *this, but we can avoid making a copy, by doing the addition top-to-bottom.

template<typename C >

void atlas::polynomials::Safe_Poly< C >::safeAdd	(	const Safe_Poly< C > &	p,
		Degree	d = 0
	)

template<typename C >

void atlas::polynomials::Safe_Poly< C >::safeDivide

(

C

c

)

Divides polynomial by scalar c, throwing an error is division is inexact.

template<typename C >

void atlas::polynomials::Safe_Poly< C >::safeQuotient

d = 0

)

template<typename C >

void atlas::polynomials::Safe_Poly< C >::safeSubtract	(	const Safe_Poly< C > &	q,
		Degree	d,
		C	c
	)

Subtracts x^d.c.q from *this, watching for underflow, assuming |c>0|.

NOTE: may forward a NumericUnderflow exception.

NOTE: q = *this is possible only for d = 0; still, we do the prudent thing and subtract backwards.
