valarray::operator/=

Visual Studio 2005

Divides an operand valarray element-wise by the elements of a specified valarray or a value of the element type.

```
valarray<Type>& operator/=(
const valarray<Type>& _Right
);
valarray<Type>& operator/=(
const Type& _Right
);
```

Parameters

_Right

The valarray or value of an element type identical to that of the operand valarray that is to be divided, element-wise, into the operand valarray.

A valarray whose elements are the element-wise quotient of the operand valarray divided by _Right.

```// valarray_op_ediv.cpp
// compile with: /EHsc
#include <valarray>
#include <iostream>

int main( )
{
using namespace std;
int i;

valarray<double> vaL ( 6 ), vaR ( 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 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;

vaL /= vaR;
cout << "The element-by-element result of "
<< "the quotient is the\n valarray: ( ";
for (i = 0 ; i < 6 ; i++ )
cout << vaL [ i ] << " ";
cout << ")." << endl;
}
```

Output

```The initial 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 ).```
