In this tutorial, we will learn about round function in C programming language
In the C Programming Language, the round() returns the nearest integer value of the float/double/argument passed to this function.
Syntax
The syntax of the round() in C language
double round (double x); float round(float x); long double round(long double x);
x is the parameter or argument of this function – x is a floating point value for find round value.
when a value for x is passed, this function returns the rounded value of x
In the C Programming Language, the required header file for the round() is
#include <math.h>
The following example explains the usage of c language round() function
#include <stdio.h>
#include <math.h>
int main()
{ //Define temporary variable
float i=5.2,j=6.8;
//calculate and display round value
printf("round value of %f is: %f\n",i,round(i));
printf("round value of %f is: %f\n",j,round(j));
return 0;
}
When the above program is compiled and run, it will produce the following result
round value of 5.200000 is: 5.000000
round value of 6.800000 is: 7.000000
