Round()

The Round() function in Go is used to round a given number to the nearest integer. This function is part of the math package, and the package must be imported to use the function in a Go program.

Syntax

result := math.Round(x)

Where:

• x: is the number to be rounded.
• result: is the rounded value returned as a float64.

Example

The following example demonstrates how to use the Round() function to round a number and print the result:

package main

import (
  "fmt"
  "math"
)

func main() {
  number := 3.7
  rounded := math.Round(number)
  fmt.Printf("Rounded value: %.0f\n", rounded)
}

The output will be:

Rounded value: 4
