Swift Double精度丢失的问题

// %.10f 情况下，2376770.3800000000 会变成 2376770.3799999999
let text2 = String.init(format: "%.10f", text1.doubleValue)

        let value1 = 0.1 + 0.2                                      // 应该等于0.3
        
        let text1 = String(value1)
        print(text1)                                                        // 打印值：0.30000000000000004
        
        let text2 = String.init(format: "%.10f", value1)            // 打印值：0.3000000000
        print(text2)
        
        let text3 = String.init(format: "%.17f", value1)            // 打印值：0.30000000000000004
        print(text3)
        
        let formatter = NumberFormatter()
        formatter.numberStyle = .decimal
        formatter.maximumFractionDigits = 10
        let text4 = formatter.string(for: value1)
        print(text4!)                                               // 打印值：0.3
