C++ round function is defined as a mathematical function returns the integral value or in layman terms, this function is used to round off any given data type like double, float except string type to the nearest integral value. This round() is defined under the cmath.h header file.So, in...
round() function is a library function of cmath header, it is used to round the given value that is nearest to the number with halfway cases rounded away from zero, it accepts a number and returns rounded value.SyntaxSyntax of round() function:round(x); ...
It is defined in the cmath header file. Example #include <iostream> #include <cmath> using namespace std; int main() { // display integral value closest to 15.5 cout << round(15.5); return 0; } // Output: 16 Run Code round() Syntax The syntax of round() function is: round...
Function Objective The ROUND function is a powerful tool for rounding numbers based on a specified number of digits. Whether you need to round up or round down, this function has you covered. Syntax The syntax for the ROUND function is as follows: =ROUND (number, num_digits) Arguments Expla...
The ROUND function syntax has the following arguments: numberRequired. The number that you want to round. num_digitsRequired. The number of digits to which you want to round the number argument. Remarks Ifnum_digitsis greater than 0 (zero), then number is rounded to the specified number of...
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. C++ lround() C++ lround() returns the long int value nearest to the given value. ...
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
Following is the basic example that illustrate the usage of C library round() function.Open Compiler #include <stdio.h> #include <math.h> int main() { double n1 = 8.6; double n2 = 6.2; double n3 = -31.6; double n4 = -32.2; double n5 = 32.5; double n6 = -12.5; printf("round...
ROUND function Rounds a number to a specified number of digits. Syntax ROUND(number,num_digits) NumberIs the number you want to round. Num_digitsSpecifies the number of digits to which you want to round the number. Remarks If num_digits is greater than 0 (zero), then number is rounded ...
If this function success, the return value is the number of steps determined after the rounding, otherwise a negative value will be returned. Examples EX1 voidRoundLimits_ex1(){doublex1=-23.4;doublex2=235.89;doublexinc;intnSteps=RoundLimits(&x1,&x2,&xinc);printf("After rounding, the result...
