div, ldiv, lldiv --
compute the quotient and remainder
div_t div(int numer, int denom);
ldiv_t ldiv(long int numer, long int denom);
lldiv_t lldiv(long long numer, long long denom);
div computes the quotient and remainder of the division of
the numerator numer by the denominator denom.
This function provides a well-defined semantics for the signed integral
division and remainder operations, unlike the implementation-defined
semantics of the built-in operations.
The sign of the resulting quotient is that of the algebraic quotient, and,
if the division is inexact,
the magnitude of the resulting quotient is the largest integer less than the
magnitude of the algebraic quotient.
If the result cannot be represented, the behavior is undefined; otherwise,
quotient denom + remainder will equal numer.
div returns a structure of type div_t, comprising both the
quotient and remainder.
Its members are:
int quot; /*quotient*/
int rem; /*remainder*/
ldiv is similar to div, except that the arguments and the members
of the returned structure (which has type ldiv_t) all have type
lldiv is similar to div, except that the arguments and the members
of the returned structure (which has type lldiv_t) all have type
