ldiv
---divide two long integers#include <stdlib.h> ldiv_t ldiv(long n, long d);Description
ldiv_t
.
Returns
The result is represented with the structure
typedef struct { long quot; long rem; } ldiv_t;
where the quot
field represents the quotient, and rem
the
remainder. For nonzero d, if `r = ldiv(n,d);
' then
n equals `r.rem + d*r.quot
'.
When d is zero, the quot
member of the result has the same
sign as n and the largest representable magnitude.
To divide int
rather than long
values, use the similar
function div
.
Portability
ldiv
is ANSI, but the behavior for zero d is not specified by
the standard.
No supporting OS subroutines are required.
