List of Scalar Data Types

Question

Im looking for a list of all the scalar data types in Objective C, complete with their ranges (max/min values etc).

Sorry for the simple question, Im just really struggling to find anything like this.

Answer 1

• int An integer value between +/– 2,147,483,647.
• unsigned int An integer value between 0 and 4,294,967,296.
• float A floating point value between +/– 16,777,216.
• double A floating point value between +/– 2,147,483,647.
• long An integer value varying in size from 32 bit to 64 bit depending on architecture.
• long long A 64-bit integer.
• char A single character. Technically it’s represented as an int.
• BOOL A boolean value, can be either YES or NO.
• NSInteger When compiling for 32-bit architecture, same as an int, when compiling for 64-bit architecture,+/– 4,294,967,296.
• NSUInteger When compiling for 32-bit architecture, same as an unsigned int, when compiling for 64-bit architecture, value between 0 and 2^64
