How to convert String to Float in Go ?

Answer

To convert a string to float in Go, you can use the 'strconv.ParseFloat()' function.

✐ Examples

1 Convert "3.14" String to Float

In this example,

We create a string variable str1 with a value of "3.14".
We use the strconv.ParseFloat() function to convert the string to a float, specifying the bit size (64 for float64) and store the result in a variable float1.
Finally, we print the float value float1.

Go Program

// Convert "3.14" String to Float
package main
import (
    "fmt"
    "strconv"
)
func main() {
    str1 := "3.14"
    float1, _ := strconv.ParseFloat(str1, 64)
    fmt.Printf("Float value is: %f", float1)
}

Output

Float value is: 3.140000

2 Convert "10.5" String to Float

In this example,

We create a string variable str2 with a value of "10.5".
We use the strconv.ParseFloat() function to convert the string to a float, specifying the bit size (64 for float64) and store the result in a variable float2.
Finally, we print the float value float2.

Go Program

// Convert "10.5" String to Float
package main
import (
    "fmt"
    "strconv"
)
func main() {
    str2 := "10.5"
    float2, _ := strconv.ParseFloat(str2, 64)
    fmt.Printf("Float value is: %f", float2)
}

Output

Float value is: 10.500000
