Go rounding utility

go get github.com/unixlinuxgeek/round

Example:

package main

import (
	"fmt"
	"github.com/unixlinuxgeek/rounding"
)

func main() {
	ceil := rounding.Ceil(1.12345678)
	fmt.Printf("ceil: %.2f\n", ceil)

	rnd := rounding.Round(1.12345678)
	fmt.Printf("round: %.2f\n", rnd)

	fl := rounding.Floor(1.12345678)
	fmt.Printf("floor: %.2f\n", fl)
}

Run tests:

go test -test.v

Example:

$ go test -test.v
