SE-0277 introduced a new half-precision floating point type called Float16, which is commonly used in graphics programming and machine learning.
This new floating-point type fits in alongside Swift’s other similar types:
let first: Float16 = 5
let second: Float32 = 11
let third: Float64 = 7
let fourth: Float80 = 13
