imaxdiv(3) |

div, ldiv, lldiv, imaxdiv − compute quotient and remainder of an integer division
#include <stdlib.h>
div_t
div(int numerator, int
denominator);
ldiv_t ldiv(long numerator, long
denominator);
lldiv_t lldiv(long long numerator, long
long denominator);
#include <inttypes.h>
imaxdiv_t imaxdiv(intmax_t numerator, intmax_t denominator);
The div() function computes the value numerator/denominator and returns the quotient and remainder in a structure named div_t that contains two integer members (in unspecified order) named quot and rem. The quotient is rounded towards zero. The result satisfies quot*denominator+rem = numerator.
The ldiv() and lldiv() and imaxdiv() functions do the same, dividing numbers of the indicated type and returning the result in a structure of the indicated name, in all cases with fields quot and rem of the same type as the function arguments.
The div_t (etc.) structure.
After
div_t q = div(−5, 3);
the values q.quot and q.rem are −1 and
−2, respectively.
SVr4, 4.3BSD, C89. The functions lldiv() and imaxdiv() were added in C99.
