Do also:

[decimalFormatter setRoundingIncrement:[NSNumber numberWithDouble:0.01]];

That is also required by the ICU algorithms that underlie NSNumberFormatter.

Does anyone know if there is a bug in the setRoundingMode:NSNumberFormatterRoundHalfUp style? Here is a code fragment I'm using:

[NSNumberFormatter setDefaultFormatterBehavior:NSNumberFormatterBehavior10_4];
decimalFormatter = [[[NSNumberFormatter alloc] init] autorelease];
[decimalFormatter setNumberStyle:NSNumberFormatterDecimalStyle];
[decimalFormatter setRoundingMode:NSNumberFormatterRoundHalfUp];
[decimalFormatter setMinimumFractionDigits:2];
[decimalFormatter setMaximumFractionDigits:2];


		[amount10_4 setFormatter:decimalFormatter];

It behaves like setRoundingMode:NSNumberFormatterRoundHalfEven when I put in .125 I get .13 and .135 I get .14. Everything else seems to work correctly for 10.4 behavior (except the currency style which is forcing the entry of a localized currency sign, but that one I've read about).

Peace,
