You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: account_balance.go
    path of file: ./repos/ethereum-development-with-go-book/code
    
    the code of the file until where you have to start completion: package main

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

	"github.com/ethereum/go-ethereum/common"
	"github.com/ethereum/go-ethereum/ethclient"
)

func main() {
	client, err := ethclient.Dial("https://cloudflare-eth.com")
	if err != nil {
		log.Fatal(err)
	}

	account := common.HexToAd
    
func main() {
	client, err := ethclient.Dial("https://cloudflare-eth.com")
	if err != nil {
		log.Fatal(err)
	}

	account := common.HexToAddress("0x71c7656ec7ab88b098defb751b7401b5f6d8976f")
	balance, err := client.BalanceAt(context.Background(), account, nil)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(balance) // 25893860171173005034

	blockNumber := big.NewInt(5532993)
	balanceAt, err := client.BalanceAt(context.Background(), account, blockNumber)
	if err != nil {
		log.Fatal(err)
	}
	fmt.Println(balanceAt) // 25729324269165216042

	fbalance := new(big.Float)
	fbalance.SetString(balanceAt.String())
	ethValue := new(big.Float).Quo(fbalance, big.NewFloat(math.Pow10(18)))
	fmt.Println(ethValue) // 25.729324269165216041

	pendingBalance, err := client.PendingBalanceAt(context.Background(), account)
	fmt.Println(pendingBalance) // 25729324269165216042
}
