The members of the enumeration and their values are declared and assigned as before. If you’re handling money, you may wish to consider using a fixed point or decimal representation. However, consistency, ease of porting, and “impedance match” are also goals and thus most bit quantities in the API are growing to 64 bits. The “integer” methods have parameter or return types of NSInteger or NSUInteger while the “int” methods accept or return values of the native types int or unsigned int. Selector “Restart” , forControlEvents: I was trying to call NSInteger and friends “architecture specific types”, which is probably wrong.

It works for me. As a beginner myself, I definitely want to know too! More information CGFloat-based math functions? The Cocoa bit changes fall into three major categories: If someone as a good technical answer. Email Required, but never shown.

Sign up or log in Sign up using Google. To maintain binary compatibility with bit applications, they are declared in the Foundation header file NSObjCRuntime.

These methods are counterparts to other methods in the same class with “int” in their names; these methods need to continue dealing with values that are specifically int. I tried the code and it works perfectly fine without any errors.

objective c – NSNumber from CGFloat – Stack Overflow

Stack Overflow works best with JavaScript enabled. On some it’s a long. It just seems like such a hassle The bit changes to the Cocoa API are largely targeted msinteger those parameter and return types required for bit addressing.

dgfloat And if it was that way, NSInteger vs int, what is your opinion then? Needless to say, this situation presents obstacles for binary compatibility.


NSNumber is used mainly for wrapping and converting primitive values, like when you want to store integers in a dictionary. I down voted it because IMHO you are nsintdger over thinking. You also might want to maintain a source base that ensures binary compatibility and source compatibility for both bit and bit architectures.

To solve this, all you have to do, is to put floor width in parentheses like this: Is this why I was downvoted?

Casting int to float

The use of some of the other primitive C types in the Cocoa API are changing in the bit initiative, while others are unaffected. Okay, as you mentioned strict compiler settings, I tried again and found the solution. You can use this instead of valueForKey and avoid using as!

Yes, but you waste cycles to convert between float and double on platforms where CGFloat is a float. V Jun 12 ’13 at Get an ad-free experience with special benefits, and directly support Reddit.

In Xcode, the ro is complaining about the following cast: Sign up ndinteger Email and Password. Apple recommends using their typedefs. To submit a product bug or enhancement request, please visit the Bug Reporter page.

The error message is incorrect possibly due to a compiler bug. Looking for work or to hire? Besides when you need a specific number of bits, that’s understandable. For example, instead of this:. Want to add to the discussion? Terms of Use Privacy Policy Updated: How helpful is this document?


This can sometimes help. These two types now replace most occurrences of int and unsigned int in the framework headers. Submit a new text post. The usual arithmetic conversions are implicitly performed to cast their values in a common type.

I’m on my way to a wedding. General Swift Discussion irc. Type conversions can be implicit which is performed by the compiler automatically or it can be specified explicitly through the use cgcloat the cast operator.

Where a parameter or return value in the Cocoa frameworks is a graphical quantity, CGFloat now replaces float. Is there a function for flooring that returns an int? NSNumber has the numberWithFloat: Take note that this list is live and based on most frequent questions in posts will be updated with “quicklinks”. Use floorf for nsintegeer. Intjust as you do for the Score variable above.

The base type of quantities defined as enumerations can thus change silently size to accord with the values in the enumeration. Thnaks nsintdger, I’ll use Lukas’ solution but yours is what I was searching for originally.
