import Foundation

let floatValue: Float64 = 123.45
let numberFormatter = NumberFormatter()
numberFormatter.numberStyle = .decimal

if let formattedNumber = numberFormatter.string(from: NSNumber(value: floatValue)) {
    print("转换后的字符串: \(formattedNumber)")
}

import Foundation

let floatValue: Float64 = 123.45
let stringValue = String(floatValue)
print("转换后的字符串: \(stringValue)")

import Foundation

let floatValue: Float64 = 123.45
let stringValue = String(format: "%f", floatValue)
print("转换后的字符串: \(stringValue)")
