NSNumberFormatter問題

Question

在我的應用程序中，我必須在事件人員之間共享金額，例如，我有3個人，例如RAM，RAJ，RAGHU，如果RAM在活動中投入的金額為10.00，那么我10.00/3=3.333333 3個人划分為10.00/3=3.333333 ，然后，

RAJ必須支付RAM ------------- 3.33
RAGHU必須支付RAM ------- 3.33

他從事件2的其他2個人那里得到的所有結果都在這里6.缺少0.1我如何解決此問題，我正在使用NumberStyle：NSNumberFormatterCurrencyStyle，如下所示

NSNumberFormatter *numberFormater = [[NSNumberFormatter alloc] init];
[numberFormater setLocale:[NSLocale currentLocale]];
[numberFormater setNumberStyle:NSNumberFormatterCurrencyStyle];
NSString *str_num = [numberFormater stringFromNumber:[NSNumber numberWithDouble:3.333333]];
[numberFormater release];

Answer 1

為什么不從10中減去RAM的份額？ 10-3.33 = 6.67。

Answer 2

  float invoice= 10.15;
  int num_people = 3; // sample people
  float num_to_add;
  float piece_pie;
  // now just add num_to_add to your invoice then divide by num_people
  num_to_add=num_people*.01;
  invoice=invoice+num_to_add;
  piece_pie = invoice/num_people;
