How to use rint() function to round N to an integral value in C

Answer 1

#include <stdio.h>     
#include <math.h>      

int main(int argc, char **argv)
{
	printf("rint(3.4) = %.1f\n", rint(3.4));
	printf("rint(4.7) = %.1f\n", rint(4.7));
	printf("rint(-3.4) = %.1f\n", rint(-3.4));
	printf("rint(-4.7) = %.1f\n", rint(-4.7));
	
	return 0;
}

/*
run:

rint(3.4) = 3.0
rint(4.7) = 5.0
rint(-3.4) = -3.0
rint(-4.7) = -5.0
