(since C99)

Computes the quotient and remainder of the division operation x/y.

[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
};
