golang 二进制转十进制实现方式
直接上代码
package main import ( "fmt" "math" ) func StringToIntArray(input string) []int { output := []int{} for _, v := range input { output = append(output, int(v)) } for i, j := 0, len(output)-1; i < j; i, j = i+1, j-1 { output[i], output[j] = output[j], output[i] } return output } func getInput(input string) <-chan int { out := make(chan int) go func() { for _, b := range StringToIntArray(input) { out <- b } close(out) }() return out } func sq(in <-chan int) <-chan int { out := make(chan int) var base, i float64 = 2, 0 go func() { for n := range in { out <- (n - 48) * int(math.Pow(base, i)) i++ } close(out) }() return out } func main() { input := "1010" c := getInput(input) out := sq(c) sum := 0 for o := range out { // fmt.Println(o) sum += o } fmt.Println(sum) // fmt.Println(sum / 1024 / 1024) }有疑问加站长微信联系（非本文作者）
