[Home]divides

Synopsis

template<
      typename T1
    , typename T2
    , typename T3 = integral_c<int,1>
    , ...
    , typename Tn = integral_c<int,1>
    >
struct divides
{
    typedef unspecified type;
};

Description

Returns the quotient of its arguments [1].

Definition

#include "boost/mpl/divides.hpp"

Parameters

 Parameter  Requirement  Description  
T1, T2, .., TnA model of Integral Constant

Expression semantics

 Expression  Expression type  Precondition  Semantics  Postcondition 
typedef divides<t1,t2,..,tn>::type quot;A model of Integral Constantt2::value != 0, t3::value != 0, .., tn::value != 0Equivalent to typedef integral_c<typeof(t1::value / t2::value .. / tn::value), t1::value / t2::value .. / tn::value > quot;

Complexity

Amortized constant time.

Example

typedef divides< integral_c<short,-10>, integral_c<long,3> >::type quot;
BOOST_STATIC_ASSERT(quot::value == -3));
BOOST_MPL_ASSERT_IS_SAME(quot::value_type, long);

Notes

[1] The divides metafunction can be (and is expected to be) specialized by user to work on user-defined types that do not satisfy the Integral Constant requirements. The requirements listed here are the ones imposed by the default implementation.
