How Objective-C support Java BigDecimal via Hessian?

Question

Server has a Java Bean, it has a instance variable type BigDecimal, but Objective-C cannot map it! I have tried NSNumber, but doesn't work. Does anybody know how to fix it?

Answer 1

Just Try this once may be it is usefull

    NSDecimalNumber *a = [NSDecimalNumber decimalNumberWithString:@"9999999999999999999999999999999999.99999999999"];
    NSDecimalNumber *b;
    NSDecimalNumber *half = [NSDecimalNumber decimalNumberWithString:@"999999999.9999999999"];
    b = [half decimalNumberByAdding:a]; 
    NSLog(@"The subtration :%@",b);

Answer 2

Use NSDecimalNumber instead of NSNumber.

Here is the code to convert a string to a NSDecimal

-(NSDecimal) getDecimalFromString:(NSString*)representationString {
    NSDecimal result;
    NSScanner *theScanner = [[NSScanner alloc] initWithString:representationString];
    [theScanner setLocale:[NSLocale currentLocale]];
    [theScanner scanDecimal:&result];

    return result;
}
