take the ceiling of a number in go

To take the ceiling of a number in Go, you need to import the "math" package and use the "Ceil" function.

Here's an example code block that demonstrates taking the ceiling of a given float64 number:

main.go
package main

import (
	"fmt"
	"math"
)

func main() {
	num := 3.14
	ceiling := math.Ceil(num)
	fmt.Println(ceiling) // Output: 4
}

In the example, we import the "math" package, which provides the "Ceil" function. We then define a float64 number "num" and use the "Ceil" function to calculate its ceiling value. Finally, we print the ceiling value using the "Println" function from the "fmt" package. The output of running the program will be "4".
