Declaring floats in goal c
advertisements
I'm new to Objective-C and I'm having trouble with the whole nonatomic, strong, weak, etc. I'm wondering if I will have any issues using Core Data with float values which are defined like so:
@property (nonatomic) float * rating;
@property (nonatomic) float * mRating;
Should I declare the differently?
Yes, you should declare them without asterisks:
@property (nonatomic) float rating;
@property (nonatomic) float mRating;
Asterisks indicate pointers. All Objective C classes are declared with asterisks, because instances are referred to through pointers. Primitives such as floats, ints, etc. are defined as values, i.e. without asterisks. Same goes for typedef-ed types such as CGFloat and NSInteger: scalar fields of these types should be defined without an asterisk.

Declaring floats, why is the default type double?
I am curious as to why float literals must be declared as so: float f = 0.1f; Instead of float f = 0.1; Why is the default type a double, why can't the compiler infer that it is a float from looking at the leftside of the assignment? Google only turn
Should I use decimals when using floats? Does the & ldquo; F & rdquo; Suffix required?
