Does swiftng have a new number
You're referring to the Swift programming language!
As of Swift 5.6, which was released in December 2021, the language has introduced a new numeric type called Float16
.
Float16
is a 16-bit floating-point number, which is a smaller and more efficient alternative to the traditional Float
type, which is a 32-bit floating-point number. Float16
is designed to provide better performance and memory usage in applications where precision is not critical.
Here are some key characteristics of Float16
:
- It has a smaller range than
Float
, with a maximum value of approximately 65,535 and a minimum value of approximately -65,535. - It has a lower precision than
Float
, with about 15 significant digits. - It is compatible with the IEEE 754-2008 standard for floating-point numbers.
You can use Float16
in your Swift code by declaring a variable or constant with the Float16
type, like this:
let myFloat16: Float16 = 3.14
Keep in mind that Float16
is not a replacement for Float
in all cases. If you need higher precision or a larger range, you should stick with Float
. However, if you're working with applications that require a more efficient use of memory and don't require high precision, Float16
can be a good choice.
