NSNumberFormatter问题

Question

在我的应用程序中，我必须在事件人员之间共享金额，例如，我有3个人，例如RAM，RAJ，RAGHU，如果RAM在活动中投入的金额为10.00，那么我10.00/3=3.333333 3个人划分为10.00/3=3.333333 ，然后，

RAJ必须支付RAM ------------- 3.33
RAGHU必须支付RAM ------- 3.33

他从事件2的其他2个人那里得到的所有结果都在这里6.缺少0.1我如何解决此问题，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

为什么不从10中减去RAM的份额？ 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;
