nttlTraits Method - Square

Description

Given a value x, return x².

Since squaring can often be done much faster than regular multiplication, it would be nice to be able to take advantage of this in algorithms that do a lot of squaring (e.g. fast exponentiation).   But there is no standard C++ operator for squaring.  This method provides a way to supply a squaring operation for the type T.  The default implementation for this method is regular multiplication, of course.

Signature

template<class T> T nttlTraits::Square( const T& x )

Parameters

Name	Type	Description
x	T	Some number.

Returns

( T )  x^2_.

Example

#include <nttl/nttlTraits.h> ... nttlTraits<int> tr; ... int x = 123; int s = tr.Square( x );
