C++ round() function: Here, we are going to learn about the round() function with example of cmath header in C++ programming language? Submitted by IncludeHelp, on April 27, 2019 C++ round() functionround() function is a library function of cmath header, it is used to round the given...
The round() function rounds a number to the nearest integer. If the decimal part is exactly 0.5 it rounds away from zero, to the integer with largest absolute value.The round() function is defined in the <cmath> header file.Syntax

The round() function in C++ returns the integral value that is nearest to the argument, with halfway cases rounded away from zero. It is defined in the cmath header file. Example #include <iostream> #include <cmath> using namespace std; int main() { // display integral value closest...
In a C program, unless you're using the <tgmath.h> macro to call this function, round always takes and returns a double. If you use the round macro from <tgmath.h>, the type of the argument determines which version of the function is selected. See Type-generic math for details. By...
The C++ <cmath> round() function returns an integral value that is nearest to the argument value, regardless of the current rounding mode. In halfway cases, the argument is rounded away from zero. Syntax C++11 double round (double x); float round (float x); long double round (long ...
In this C++ tutorial, you will learn how to round a given number to nearest long int value using lround() function of cmath, with syntax and examples.
