init(_:)
Creates an integer from the given floating-point value, rounding toward zero. Any fractional part of the value passed as source
is removed.

init<T>(_ source: T) where T : BinaryFloatingPoint
Parameters
- source
A floating-point value to convert to an integer.
source
must be representable in this type after rounding toward zero.
Overview
let x = Int(21.5)
// x == 21
let y = Int(-21.5)
// y == -21
If source
is outside the bounds of this type after rounding toward zero, a runtime error may occur.
let z = UInt(-21.5)
// Error: ...outside the representable range
