HarmonyOS 十进制转二进制方法

参考demo，使用.toString(2)就可以转为二进制

// xxx.ets
@Entry
@Component
struct TextTimerExample {
  textTimerController: TextTimerController = new TextTimerController()
  @State format: string = 'mm:ss.SS'
  @State sss: number = 12345

  build() {
    Column() {
      Text(this.format).onClick(() => {
        this.format = this.sss.toString(2)
      })
    }
  }
}
