operator/ (<valarray>)
Obtains the element-wise quotient between corresponding elements of two equally sized valarrays or of between a valarray a specified value.
template<class Type>
valarray<Type> operator/(
const valarray<Type>& _Left,
const valarray<Type>& _Right
);
template<class Type>
valarray<Type> operator/(
const valarray<Type>& _Left,
const Type& _Right
);
template<class Type>
valarray<Type> operator/(
const Type& _Left,
const valarray<Type>& _Right
);
Parameters
_Left
A value or valarray that serves as the dividend into which another value or valarray is to be divided in forming the quotient._Right
A value or valarray that serves as the divisor and that divides another value or valarray in forming the quotient.
Return Value
A valarray whose elements are the element-wise quotient of _Left divided by _Right.
Remarks
The arithmetic terminology used in describing a division:
quotient = dividend / divisor
Example
// valarray_op_equo.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>
int main( )
{
using namespace std;
int i;
valarray<double> vaL ( 6 ), vaR ( 6 );
valarray<double> vaNE ( 6 );
for ( i = 0 ; i < 6 ; i += 2 )
vaL [ i ] = 100;
for ( i = 1 ; i < 6 ; i += 2 )
vaL [ i ] = -100;
for ( i = 0 ; i < 6 ; i++ )
vaR [ i ] = 2*i;
cout << "The initial Left valarray is: ( ";
for ( i = 0 ; i < 6 ; i++ )
cout << vaL [ i ] << " ";
cout << ")." << endl;
cout << "The initial Right valarray is: ( ";
for ( i = 0 ; i < 6 ; i++ )
cout << vaR [ i ] << " ";
cout << ")." << endl;
vaNE = ( vaL / vaR );
cout << "The element-by-element result of "
<< "the quotient is the\n valarray: ( ";
for ( i = 0 ; i < 6 ; i++ )
cout << vaNE [ i ] << " ";
cout << ")." << endl;
}
The initial Left valarray is: ( 100 -100 100 -100 100 -100 ).
The initial Right valarray is: ( 0 2 4 6 8 10 ).
The element-by-element result of the quotient is the
valarray: ( 1.#INF -50 25 -16.6667 12.5 -10 ).
