Here, we will learn how to get Pi value in go. We can use **Pi constant of math package to get Pi value in go.**

**Constant value:**

`Pi = 3.14159265358979323846264338327950288419716939937510582097494459 `

**Example with code:**

```
package main
import (
"fmt"
"math"
)
func main() {
pi_val := math.Pi
fmt.Println("Pi value: ", pi_val)
}
```

**Output:**

```
$ go run sample.go
Pi value: 3.141592653589793
```
