Numerical Data Types
Explore Swift's numerical data types such as signed and unsigned integers, floating-point numbers, and Boolean values. Understand their sizes, precision, and usage to effectively manage numerical data in Swift programming for Apple platforms.
We'll cover the following...
Now that we have a basic understanding of the concept of data types and why they are necessary, we can take a closer look at some of the more commonly used data types supported by Swift, starting with numerical data types.
Integer data types
Swift integer data types are used to store whole numbers (in other words a number with no decimal places). Integers can be signed (capable of storing positive, negative, and zero values) or unsigned (positive and zero values only).
Swift provides support for 8, 16, 32, and 64-bit integers (represented by the Int8, Int16, Int32, and Int64 ...
