Xcode Decimal x.x.x

Question

xcode can use Decimal 3 place?

Example:

NSDecimal *test = 1.0.0; //not work
double test = 1.0.0; //not work
float test = 1.0.0; //not work

Can I use decimal 3 place in xcode?

Um, no? That's not a usual numeric notation. What are you trying to do? — Greg Hewgill, Sep 16 '13 at 03:27

Objective-C is not Java. Things don't get autoboxed without a bit more syntax than this. — CodaFi, Sep 16 '13 at 03:41

Version numbers like 1.0.3 are neither floating point nor decimal numbers. If you need to store them in a variable, use a string:

NSString *test = @"1.0.0";

Ah, so you want to *compare* version numbers. Why didn't you say so in your question! – Greg Hewgill Sep 16 '13 at 03:51

Comparing version strings is pretty hard actually. Sparkle has some open source code to do it. – Catfish_Man Sep 16 '13 at 03:52

Use string and componentsSeparatedByString: method and then convert each object in array to appropriate format.
