SYNOPSIS |
#include <stdlib.h> div_t div(int numer, int denom);
DESCRIPTION |
div
computes the quotient and remainder of
numer
divided by
denom
.
RETURN VALUE |
div
returns a structure of type
div_t
, which
contains both the quotient and remainder. The definition of the
div_t
type is
typedef struct { int rem; int quot; } div_t;
numer == quot * denom + rem
The sign of
rem
is
the same as the sign of
numer
.
EXAMPLE |
This example converts an angle in radians to degrees, minutes, and seconds:
#include <math.h> #include <stdlib.h> #include <lcmath.h> main() { double rad, angle; int deg, min, sec; div_t d; puts(" Enter any angle in radians: "); scanf("%lf", &rad); /* Convert angles to seconds and discard fraction. */ angle = rad * (180 * 60 * 60)/M_PI; sec = angle; d = div(sec, 60); sec = d.rem; d = div(d.quot, 60); min = d.rem; deg = d.quot; printf("%f radians = %d degrees, %d', %d", \n", rad, deg, min, sec); }
