NSNumberFormatter returns negative numbers for unsigned long long n such
that (LLONG_MAX + 1) <= n <= ULLONG_MAX. Am I doing something incorrect, or
should I report this as a bug?
- (void)awakeFromNib
{
NSNumberFormatter *formatter = [[NSNumberFormatter alloc] init];
[formatter setFormatterBehavior:NSNumberFormatterBehavior10_4];
[formatter setFormat:@"#,##0; -#,##0"];
unsigned long long uLLongMax = ULLONG_MAX; // debugger shows
18446744073709551615
NSNumber *uLLongMaxNumber = [NSNumber
numberWithUnsignedLongLong:uLLongMax]; // debugger shows
18446744073709551615
NSString *uLLongMaxString = [formatter
stringFromNumber:uLLongMaxNumber]; // debugger shows -1
[unsignedLongLongTextField setStringValue:uLLongMaxString];
unsigned long long lLongMax = (unsigned long long)LLONG_MAX; //
debugger shows 9223372036854775807
NSNumber *lLongMaxNumber = [NSNumber
numberWithUnsignedLongLong:lLongMax]; // debugger shows
9223372036854775807
NSString *lLongMaxString = [formatter stringFromNumber:lLongMaxNumber];
// debugger shows 9,223,372,036,854,775,807
[unsignedLongLongTextField2 setStringValue:lLongMaxString];
unsigned long long lLongMaxPlusOne = (unsigned long long)LLONG_MAX + 1;
// debugger shows 9223372036854775808
NSNumber *lLongMaxPlusOneNumber = [NSNumber
numberWithUnsignedLongLong:lLongMaxPlusOne]; // debugger shows
9223372036854775808
NSString *lLongMaxPlusOneString = [formatter
stringFromNumber:lLongMaxPlusOneNumber]; // debugger shows
-9,223,372,036,854,775,808
[unsignedLongLongTextField3 setStringValue:lLongMaxPlusOneString];
}
Thanks in advance.
