Function Documentation

template<typename C> bool atlas::polynomials::compare (  const Polynomial< C > &  p, const Polynomial< C > &  q )

Polynomial comparison. Explanation: p < q if deg(p) < deg(q), or if degrees are equal, and the comparison holds for coefficients, in lex-order starting from the top. Definition at line 289 of file polynomials_def.h. References atlas::polynomials::Polynomial< C >::degree(), and atlas::polynomials::Polynomial< C >::isZero(). Referenced by atlas::bitvector::normalize().

template<typename C> void atlas::polynomials::safeAdd (  C &  a, C  b )

a += b. Throws a NumericOverflow exception in case of overflow. Definition at line 325 of file polynomials_def.h. Referenced by atlas::polynomials::Polynomial< C >::safeAdd().

template<typename C> void atlas::polynomials::safeProd (  C &  a, C  b )

a *= b. Throws a NumericOverflow exception in case of overflow. Definition at line 342 of file polynomials_def.h. Referenced by atlas::polynomials::Polynomial< C >::safeAdd(), and atlas::polynomials::Polynomial< C >::safeSubtract().

template<typename C> void atlas::polynomials::safeSubtract (  C &  a, C  b )

a -= b. Throws a NumericUnderflow exception in case of underflow. Definition at line 362 of file polynomials_def.h. Referenced by atlas::polynomials::Polynomial< C >::safeSubtract().
