# std::div, std::ldiv, std::lldiv

From cppreference.com
< cpp‎ | numeric‎ | math

Defined in header `<cstdlib>` |  |
std::div_t div( int x, int y ); |  |
std::ldiv_t div( long x, long y ); |  |
std::lldiv_t div( long long x, long long y ); |  | (since C++11)
std::ldiv_t ldiv( long x, long y ); |  |
std::lldiv_t lldiv( long long x, long long y ); |  | (since C++11)
Defined in header `<cinttypes>` |  |
std::imaxdiv_t div( std::intmax_t x, std::intmax_t y ); |  | (since C++11)
std::imaxdiv_t imaxdiv( std::intmax_t x, std::intmax_t y ); |  | (since C++11)

Computes quotient and remainder simultaneously.

The quotient is the algebraic quotient with any fractional part discarded (truncated towards zero). The remainder is such that quot * y + rem == x. | (until C++11)
The quotient is the result of the expression x/y. The remainder is the result of the expression x%y. | (since C++11)

### [edit] Parameters

x, y | - | integer values

### [edit] Return value

Structure of type `div_t`, `ldiv_t`, `ldiv_t`, `imaxdiv_t` defined as:

    struct div_t {
        int quot;   // The quotient
        int rem;    // The remainder
    };

    struct ldiv_t {
        long quot;   // The quotient
        long rem;    // The remainder
    };

    struct lldiv_t {
        long long quot;   // The quotient
        long long rem;    // The remainder
    };

    struct imaxdiv_t {
        std::intmax_t quot;   // The quotient
        std::intmax_t rem;    // The remainder
    };

### [edit] Notes

Until C++11, the rounding direction of the quotient and the sign of the remainder in the built-in division and remainder operators was implementation-defined if either of the operands was negative, but it was well-defined in std::div.
