valarray::operator/=

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.

Return Value

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

Example

// 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;
}

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 ).
