Question

我正在寻找一种在Swift 3中将小数二进制部分转换为小数部分的方法。此代码将二进制整数转换为十进制

也许有相同的解决方法但仅适用于小数部分？

例如： 101.0101至5.3125（十进制）

Answer 1

一旦遇到小数点，就必须切换为结果增加1/2的权力：

func fractionalBinaryToDecimal(bin: String) -> Double? {
    var result = 0.0
    var inFractionalPart = false // Set to `true` if the decimal point is encountered
    var fractionalValue = 1.0 // Current power of 1/2 when adding the fractional part

    for digit in bin.characters { // Swift 4: for digit in bin { ...
        switch digit {
        case "0":
            if inFractionalPart {
                fractionalValue /= 2.0
            } else {
                result = 2 * result
            }
        case "1":
            if inFractionalPart {
                fractionalValue /= 2.0
                result += fractionalValue
            } else {
                result = 2 * result + 1
            }
        case ".":
            guard !inFractionalPart else { return nil } // Repeated decimal point
            inFractionalPart = true
        default:
            return nil // Invalid digit
        }
    }

    return result
}

示例：

if let val = fractionalBinaryToDecimal(bin: "101.0101") {
    print(val) // 5.3125
}

如何在Swift 3中将小数二进制转换为小数？
