NSNumberFormatter问题

Question

在我的应用程序中，我必须在事件人之间共享数量--例如，我有三个人的名字，如RAM、RAJ、RAGHU，如果内存在事件中的数量是10.00，那么我就把它分成三个人，比如10.00/3=3.333333，

RAJ必须向RAM支付

RAGHU必须支付RAM -3.33

总之，他从事件中的其他两个人那里得到了6.66，这里缺少了0.1，我该如何解决这个问题，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

你为什么不把RAM的份额从10? 10-3.33= 6.67减去。

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;
