Here, We will learn **how to get the least integer value of a number in go. **We can get it by using **Ceil() function in math package in go golang.**

**Function prototype:**

`func Ceil(no float64) float64`

**Return value:**

Ceil() function in math package returns

the least integer value greater than or

equal to number.

**Example with code:**

```
package main
import (
"fmt"
"math"
)
func main() {
no := math.Ceil(2.51)
fmt.Printf("%.1f\n", no)
no = math.Ceil(2.39)
fmt.Printf("%.1f\n", no)
no = math.Ceil(3.12)
fmt.Printf("%.1f\n", no)
no = math.Ceil(-3.21)
fmt.Printf("%.1f\n", no)
}
```

**Output:**
