floor: returns the largest integer (represented as a floating-point value) not greater than num





    



//Declaration: float floorf(float num); 

               double floor(double num); 

               long double floorl(long double num);  

//Return:      Given 1.02, floor() would return 1.0.

               Given -1.02, floor() would return -2.0.

    

  



  #include <math.h>

  #include <stdio.h>



  int main(void)

  {



    printf("%f", floor(10.9));

 

  }
