Scan is a support routine for fmt.Scanner. It accepts the formats 'e', 'E', 'f', 'F', 'g', 'G', and 'v'. All formats are equivalent.

Go
Edit 
package main

import (
	"fmt"
	"log"
	"math/big"
)

func main() {
	// The Scan function is rarely used directly;
	// the fmt package recognizes it as an implementation of fmt.Scanner.
	r := new(big.Rat)
	_, err := fmt.Sscan("1.5000", r)
	if err != nil {
		log.Println("error scanning value:", err)
	} else {
		fmt.Println(r)
	}
}
