Int to Float in Go

In Go, we can convert an integer to a float by simply assigning the integer to a variable of the float type. Here's an example:

package main
import "fmt"
func main() {

    // Converting an integer to a float

    var x int = 10

    var y float64 = float64(x)

    fmt.Println(y)

}

In the example above, we first declare an integer variable x and assign it the value 10. We then declare a float64 variable y and assign it the value of x after it has been converted to a float.

Alternatively, we can also use the strconv package to convert an integer to a float. Here's an example:

package main
import (

    "fmt"

    "strconv"

)
func main() {

    // Converting an integer to a float using strconv

    var x int = 20

    var y float64

    y, _ = strconv.ParseFloat(strconv.Itoa(x), 64)

    fmt.Println(y)

}

In this example, we first declare an integer variable x and assign it the value 20. We then declare a float64 variable y. We use the strconv.Itoa function to convert the integer x to a string, then we use the strconv.ParseFloat function to convert the string to a float64, which we assign to y. The second argument to strconv.ParseFloat is the bit size (64 in this case), and the underscore before it is used to ignore any error returned by the function.
