    Parameters

    source

    A floating-point value to convert to an integer. source must be representable in this type after rounding toward zero.

    Any fractional part of the value passed as source is removed, rounding the value toward zero.

    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: ...the result would be less than UInt.min
