How to Directly Convert a float64 to an int in Go?

Direct Conversion from float64 to int in Go

In Go, converting a float64 number to an integer can be achieved directly using type casting syntax. Simply enclose the float64 variable within an int( ) type assertion to obtain the nearest integer.

Consider the following code snippet:

package main

import "fmt"

func main() {
  var x float64 = 5.7
  var y int = int(x)
  fmt.Println(y)  // outputs "5"
}

In this example, we define a float64 variable x with the value 5.7. We then use the type assertion int(x) to convert it to an integer and store it in the int variable y. When we print the value of y, it displays 5, which is the nearest integer to 5.7.

This approach eliminates the need for intermediate string conversions, resulting in a more efficient and straightforward conversion process. Keep in mind that this conversion may result in loss of precision for non-integer values.
