problems with NSDoubleNumber

[David Wetzel]

Hi,

this code has been working before and is working on OS, but this is current 
(svn) -base:

// string is @"6.69"
 price = (NSDecimalNumber*) [NSDecimalNumber numberWithDouble:[myString 
doubleValue]];    
 price = (NSDecimalNumber*) [price decimalNumberByDividingBy:[NSDecimalNumber 
numberWithInt:100]];    


(<NSException: 0x7f7ff88e3e60> NAME:NSInvalidArgumentException 
REASON:NSDoubleNumber(instance) does not recognize decimalNumberByDividingBy: 
INFO:(nil))


(gdb) po self
6.69
(gdb) po [self class]
NSDoubleNumber
---------------------------------------

If I would use decimalNumberWithString:locale: what is the currently best way 
to do this with a '.' separator?
This is a web app so the user settings might become irrelevant.

Thanks!
