Float.Scan in Go

Scan is a support routine for fmt.Scanner; it sets z to the value of the scanned number. It accepts formats whose verbs are supported by fmt.Scan for floating point values, which are: 'b' (binary), 'e', 'E', 'f', 'F', 'g' and 'G'. Scan doesn't handle ±Inf.

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.
	f := new(big.Float)
	_, err := fmt.Sscan("1.19282e99", f)
	if err != nil {
		log.Println("error scanning value:", err)
	} else {
		fmt.Println(f)
	}
}
