golang 二进制转十进制实现方式

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)
}
