我有以下代码

(...)
numberStyle = [NSDecimalNumberHandler decimalNumberHandlerWithRoundingMode:NSRoundPlain
                                                                     scale:2
                                                          raiseOnExactness:NO
                                                           raiseOnOverflow:NO
                                                          raiseOnUnderflow:NO
                                                       raiseOnDivideByZero:NO];

strThree = textFieldThree.text;
strThree = [strThree stringByReplacingOccurrencesOfString:@"." withString:@""];

fieldOneDNa = (NSDecimalNumber *)[NSDecimalNumber decimalNumberWithString:strThree];
oneHundred = (NSDecimalNumber *)[NSDecimalNumber decimalNumberWithString:@"100"];
fieldOneDN = [fieldOneDNa decimalNumberByDividingBy:oneHundred
                                       withBehavior:numberStyle];

firstStepReturn = [fieldOneDN stringValue];
textFieldThree.text = firstStepReturn;
(...)

我希望能够让firstStepReturn在小数点后面有2位数,即使它们是.00或.*0.例如,如果323.390被输入到文本字段"textFieldThree"中,它将被处理并返回到文本字段3233.90.目前,它显示为3233.9.

任何帮助将不胜感激.
