Floor function is used to get nearest integer less than equal to the entered number or number stored in variable.This function is included in math.h header file to access this function we have to add "#include<math.h>".Let us see how to use this function by an simple example.
Example:
#include<stdio.h>
#include<conio.h>
#include<math.h>
main()
{
float b=10.5,c=-9.34;
clrscr();
printf("The floor of b is %f",floor(b));
printf("\nThe floor of c is %f",floor(c));
getch();
}
Example:
#include<stdio.h>
#include<conio.h>
#include<math.h>
main()
{
float b=10.5,c=-9.34;
clrscr();
printf("The floor of b is %f",floor(b));
printf("\nThe floor of c is %f",floor(c));
getch();
}
