template<class T >
T Min ( const T &  a_a,
const T &  a_b 
)
inline

Returns a copy of the minimum of the two values. Will work with any type T that supplies a T::operator<(const T, const T), or an equivalent construct, as well as a copy constructor. In particular, it will work with any integral or floating-point intrinsic type.

Referenced by IFData< dim >::BrentRootFinder(), EBPatchAdvect::floorPrimitives(), RealVect::min(), and IntVect::min().

template<class T >
T Max ( const T &  a_a,
const T &  a_b 
)
inline

Returns a copy of the maximum of the two values. Will work with any type T that supplies a T::operator>(const T, const T), or an equivalent construct, as well as a copy constructor. In particular, it will work with any integral or floating-point intrinsic type.

template<class T >
T Abs ( const T &  a_a)
inline

Returns a copy of the absolute value of the value. Will work with any type T that can be compared against zero with T::operator>(const T, const T), or an equivalent construct, as well as a copy constructor, and an T::operator-() or equivalent. In particular, it will work with any integral or floating-point intrinsic type.

template<class T >
void Swap ( T &  a_a,
T &  a_b 
)
inline

Swaps the two values. Type T must have a copy constructor and an assignment operator.
