How can we truncate float64 type to a particular precision?

Question

package main

import (
    \"fmt\"
    \"strconv\"
    )

func main() {
    k := 10/3.0
    i := fmt.Sprintf(\"%.2f\", k)
    f,_ := strconv.ParseFloat(i, 2)
    fmt.Pri

Be careful with longitude and latitude float as truncating and rounding can yield completely different results... as it can put you on the wrong side of a latitude boundary.
