floating-point remainder value function
#include <math.h>
#include <stdio.h>
int main(void)
{
printf("%1.1f", fmod(10.0, 3.0));
return 0;
}
Mod and divide
#include <stdio.h>
int main(void)
{
printf("%d", 7/2);
printf(" %d", 7%2);
printf(" %d", 4/2);
printf(" %d", 4%2);
return 0;
}
Return remainder of floating point division: fmod
#include <stdio.h>
#include <math.h>
int main ()
{
printf ("fmod of 6.3 / 2 is %lf\n", fmod (6.3,2) );
printf ("fmod of 19.5 / 4.2 is %lf\n", fmod (19.5,4.2) );
return 0;
}
Split floating-point value into fractional and integer parts: how to use modf
#include <stdio.h>
#include <math.h>
int main ()
{
double p, fractpart, intpart;
p = 3.14159265;
fractpart = modf (p , &intpart);
printf ("%lf = %lf + %lf \n", p, intpart, fractpart);
return 0;
}
Use the mod % operator
#include <stdio.h>
int main(void)
{
int i;
printf("Enter a number: ");
scanf("%d", &i);
if( ( i % 2 ) == 0)
printf("Even");
if( ( i % 2 ) ==1)
printf("Odd");
return 0;
}
