We will get highest integer less than the input data by using floor() function. Output is the nearest integer ( on lower side ) of the number.
#include <stdio.h>
#include <math.h>
int main(void){
float num; // num is declared as float variable
num=17.873; // data is stored
printf("num = %.4f", floor(num)); // final output
return 0;
}
The above code will give this output.
num = 17.0000
Example with negative value
#include
#include
int main(void){
float num; // num is declared as float variable
num=-17.873; // data is stored
printf("num = %.4f", floor(num)); // final output
return 0;
}
