Question

I have an situation where I get an NSDecimal, and I need an NSInteger. I do know it is a very small value (this is absolutely sure). It won’t be bigger than 100. So It would be perfectly fine to cast it to NSInteger, no overflow would happen.

How could this be done? There’s just an -doubleValue method in NSDecimal.

Answer 1

First convert it to an NSDecimalNumber. NSDecimalNumber is a subclass of NSNumber so you can use all of the NSNumber methods:

NSDecimalNumber *myNSDecimalNumber = [NSDecimalNumber decimalNumberWithDecimal:myNSDecimal];
NSInteger myInt = [myNSDecimalNumber intValue];
